Controllers play the following role in control system:
A. They amplify the signals going to the actuator
B. They act on the error signal coming out of the summing junction and output a suitable to the actuator
C. They try to reduce steady state error optimizes overshoot.
D. All of the mentioned
Answer:A
Controllers play the following role in control system:
A. They amplify the signals going to the actuator B. They act on the error signal coming out of the summing junction and output a suitable to the actuator C. They try to reduce steady state error optimizes overshoot. D. All of the mentioned
Explanation: Controller amplify the signals going to the actuator and they are of many types as proportional, integral, derivative some combinational controller as combination of two controllers and combination of all the controllers.
