Proportional Controllers In the proportional control algorithm, the controller output is proportional to the error signal, which is the difference between the set point and the process variable. In other words, the output of a proportional controller is the multiplication product of the error signal and the proportional gain. This can be mathematically expressed as where Pout: Output of the proportional controller Kp: Proportional gain e(t): Instantaneous process error at time 't'. e(t) = SP − PV SP: Set point PV: Process variable 30
Compensated Controllers • Compensation is a technique used to change the root locus so that it passes through a desired pole position. • This process involves the selective positioning of additional poles and zeros into the overall response of the system. • Compensation can be used to improve both the steady state error and the transient response. • Most controllers now are implemented digitally. 31
