The for loop. 8. A counter variable is used to control or keep track of the number of times a loop. iterates. In a loop, the counter is usually incremented or decremented. If the. counter variable is not properly initialized, it will not hold the correct number. 9. An accumulator is used to keep a running total of numbers. In a loop, a value is. usually added to the current value of the accumulator.
To avoid having a steady state error the proportional. controller can be change to. u(t) = Ke(t)+u b : (8.4)where u b is a bias or reset term which is adjusted to give the desired steadystate value. Integral Action Integral action guarantees that the process output agrees with the referencein steady state.hapter 8 PID Control Based on a survey of over eleven thousand controllers in the reï¬ning, chemi-cals and pulp and paper industries, 97% of regulatory controllers utilize PIDfeedback.Desborough Honeywell, 2000.
