Analysis and Simulation of the Anti-Disturbance Problem on Phase Plane Division Control

The phase plane division controller is one that according to error and error rate applies different actions in the phase plane to make the control system up to requirement. Furthermore, just as the PID control, it´s unnecessary to build up a mathematical model of the controlled object. In this paper, by adding various typical disturbance signals to the control channel, the output channel and the feedback channel in the two-order system, analysis and comparison are made of the changes in the dynamic and steady attributes, under different disturbing actions, of both the close-loop PID control and the phase plane division control. The results of the simulations show that the phase plane division control system possesses better performance of anti-disturbance
