She has been removed for allegedly bringing the party into disrepute.
Ms Patterson recently criticised the party's decision to overlook her for the South Belfast assembly seat vacated by Jimmy Spratt, and instead appointing former special adviser Emma Pengelly.
Mr Robinson said Ms Patterson has a right to appeal her expulsion.
He said party officers "unanimously decided to expel her earlier this week".
He added that he believed "there has been some correspondence" between the party and Ms Patterson since she was informed of the decision.
Ms Pengelly took her place in the Northern Ireland Assembly in September through the co-option system, which allows parties to replace departing MLAs with a party colleague without a by-election.
It has been used extensively by many of the parties in the assembly.
Within a month of her selection as an MLA for South Belfast, Ms Pengelly was appointed as a junior minister in the Office of the First Minister and deputy First Minister.
She had previously worked in the department as a special adviser to the first minister for almost nine years.
Last month, Ms Patterson, a former deputy lord mayor of Belfast, said she had been annoyed by Ms Pengelly's dual promotion.
"There is a principle, in my book, of giving someone who has earned something the chance, rather than someone who does not have one solitary vote, who has never stood for election, who has never run the gauntlet of an election," she said.
"It it not sour grapes. Anyone in my position would feel exactly the same - not surprised, but let down.
"I thought I was worth a little more."
Ms Patterson also said last month that her party's return to the Northern Ireland Executive after the publication of a report on paramilitaries had shocked her "to the core".
She said she had major difficulties with the move, and had been considering her position in the party.
Belfast councillor Ruth Patterson has been expelled from the Democratic Unionist Party (DUP), its leader Peter Robinson has told the BBC.

Judges at the Court of Appeal rejected claims that Stephen McCaughey and brothers Ian and Jason Weir received unduly lenient jail terms for their roles in the killing of Philip Strickland.
Mr Strickland was killed with a shotgun during a dispute in 2012. He was found dead in his car on the Ballydrain Road, near Comber.
The killing followed a row with farmer Jimmy Seales, the father of the Weir brothers.
Seales, 57, is serving a minimum 15-year prison term after being convicted of carrying out the murder.
McCaughey, 27, from Shackelton Walk in Newtownards, was also found guilty and ordered to serve at least 10 years behind bars.
Ian and Jason Weir, of Derryboye Road and Raffery Road, near Killinchy, had earlier pleaded guilty to murder.
During the trial, Ian Weir, 29, placed his father at the scene of the shooting, armed with a shotgun.
He received a minimum prison term of four years, while his 28-year-old brother was told he would spend at least nine and a half years in jail.
The discounted sentences were referred back to the Court of Appeal.
Senior counsel for the DPP argued all three should have been handed longer jail terms.
But senior judges ruled that none of the sentences were unduly lenient.
Lord Justice Gillen said the level of co-operation provided by Ian Weir should not be underestimated, as he gave evidence against his father, "a man who had bullied and dominated him and his brother for many years".
He said: "Such evidence against a close family member is invaluable and not easily obtained."
He also held that Jason Weir played a secondary role in the killing, compared to his father.
McCaughey, the judge said, became involved out of a "foolish, mistaken sense of loyalty" to one of the Weirs, with no evidence of him carrying out any physical attack.
The Director of Public Prosecutions (DPP) has failed in a bid to have three murderers' prison sentences increased.

There are 30 huge men on the pitch, many of them weighing north of 17 or 18 stones, battering seven bells out of each other for 80 minutes, yet the coaches insist it's the little things that make the difference.
They were at it again on Friday, Wales' smiling coach Rob Howley and his sharp, clear-talking Ireland counterpart Joe Schmidt.
A seething crowd of 74,500 witnessed Wales' redemptive 22-9 victory over Ireland in a thrilling, bruising, hide-behind-the-hands Test match in Cardiff.
And while Howley - under intense pressure in the build-up to the match - talked about how different the tournament would have been if little things had gone Wales' way in the 23-16 defeat by England, Schmidt smiled ruefully on how Ireland had been undone by minor incidents with a major impact.

So what little things? Well here are four key moments from another epic Six Nations Friday in Cardiff.
Ireland were leading 3-0 and asking most of the questions when fly-half Johnny Sexton left the field for a head injury assessment after taking an accidental blow from Jonathan Davies.
With his temporary replacement Paddy Jackson still settling in to place, Wales attacked down the fly-half channel through Rhys Webb and Scott Williams to create the first of George North's two tries.
"It was very smart of Wales to attack down that channel and difficult for Paddy who had just come on," said Schmidt.
It was early in the match and gave Wales just a two-point advantage which Jackson quickly cancelled with a penalty, but it ignited the crowd and put a spring in the step of the Wales backs.
Schmidt pointed out after the game that Wales were penalised 10 times to Ireland's four, yet it was Johnny Sexton who saw yellow.
The key wasn't the crime itself but where it was committed - right on Ireland's try line with Wales attacking furiously.
Sexton marched off with minutes of the first half remaining and Wales trailing 6-5. By the time he returned Wales were leading 15-6 after Webb - again - had exploited Wales' extra man to give George North an unopposed run-in in the right corner.
"I felt Johnny was unlucky because he was pinned by three Welsh players, but in those areas and circumstances there's always a danger of a yellow," said Schmidt.
Howley felt Wales exploited the extra man well.
"The try down the short side in the second half was very smart," was the former Wales scrum-half's view.
With Sexton orchestrating a siege on Wales' goal-line and the home team defending a six-point lead Dan Biggar had a clearance from the in-goal area charged down.
The deflection flew to prop Tadhg Furlong and straight through his fingers with the try line at his mercy. Wales scrambled the ball into touch and then survived a driving line-out.
Minutes later with Ireland eventually pinned back in their 22 and still trailing by six, Sexton's attempted chip was battered to the ground by Taulupe Faletau.
The ball ping-ponged briefly off some legs before finding its way into the grateful arms of Jamie Roberts who dragged the at-the-centre-of-everything Sexton over the line with him to score the match-clinching try.
But the key moment in the game involved an Irish driving line-out with some five minutes remaining.
Captain Rory Best had the ball under control and Ireland were making slow but steady progress towards the Wales try line before the maul was briefly halted.
Centre Robbie Henshaw's intervention added fresh trundle to the bundle of wrestling bodies and Best dropped over the Welsh try line with referee Wayne Barnes saying: "No Rory, I can't allow it."
Henshaw had entered the maul in front of Best, obstructing Welsh defenders and was penalised - a situation from which Wales eventually pinned Ireland back and claimed their decisive third try.
"If we score that it's in and around the 15-metre mark and you'd expect to convert it," said Schmidt.
"You go one point ahead and suddenly they're chasing the game and not us."
In commentary, former Ireland captain Paul O'Connell put it nicely in a probably unintentional rhyming couplet.
"If he puts his arm around Rory, it's a different story," he said.
And how!
Ireland could have been preparing for a championship showdown with England in Dublin while Wales would have been travelling to France trying to avoid their worst campaign since 2007.
Instead, Schmidt believes Ireland are playing for a place in the top half of the table while Wales are off to Paris with a spring in their step at last - a chorus of discontent replaced by cheers and back-slapping.
Little things. Major consequences. Altogether a big night out in Cardiff.

It's an oft-repeated mantra during this Six Nations tournament that international rugby matches are decided by small margins.
