Example of proportional controller

WebMar 1, 2007 · Proportional controllers tended to quit too soon when attempting to eliminate errors between the process variable and setpoint. This steady-state offset is illustrated in the graphic on page 36. Proportional controllers settle for small, but non-zero errors, leaving the process variable at a value somewhat shy of the setpoint. WebControl Systems Controllers - The various types of controllers are used to improve the performance of control systems. In this chapter, we will discuss the basic controllers such as the proportional, the derivative and the integral controllers.
