Question
Indicate whether each of the following statements is true or false (a) A first-order system with its P only controller will always have a second order dynamic (b) For proportional control, the larger the proportional band the higher the sensitivity of the controller's signal to deviation. (c) A feedback system is stable if all roots of the equation (G_Dt = 0) have negative real roots or negative real parts (d) A SISO is a Single Input System with many Outputs. (e) Servo-mechanic action of the controller is adjusting the manipulated variable appropriately to achieve follow set point changes (f) Rise time is the time required for the output to reach its first maximum value (g) All variables in a process, which are not self-regulating must be controlled h) In feed forward controller, corrective action occurs regardless of the source of disturbance. i) Knowledge of the mathematical model of a process is not required for feedback control (a) In feed forward controller, corrective action is taken before a deviation in the controlled variable occurs.Explanation / Answer
a) A first order system with its p-only controller will always have a second order dynamics.
Ans: True.
b) For proportional control the larger the proportional bad the higher the sensitivity of the controllers signal to derivation.
Ans: False.
d)A SISO is a single input system with many options
Ans: True.
f) Rise time is the required for the output to reach it's first max value.
Ans: True.
g) All variables in a process whic are not self-regulating must be controlles
Ans: False.
h) In feed forward ontroller corrective action occures regardless of source of disturbance.
Ans: false
