Research on Proportional Controller Based on Phase Plane Division

Proportional control strategy is easily realized, but the system dynamic performance, steady performance and stability are contradictory for proportional control requirement. The proportion control strategy of different partitions of the proportional controller based on phase plane partition affects system performance index. Adjusting the proportional control of the controller based on different phase plane partitions can improve some performance indexes so that overall performance indexes could be improved. The control parameters are discussed about how to affect the stability, steady performance and dynamic performance of system. Finally, the obtaining means of parameter for phase plane division proportional controller is discussed.
