P-模糊-PI滑模控制系统设计

Design on Sliding Mode Control System based on P-Fuzzy-PI Controller

针对PID控制器难以解决非线性、时变的复杂系统和模型不清楚系统的控制问题,利用模糊控制器能简单而有效地控制复杂的或模型不清楚的系统的优点,设计一种具有PID和模糊控制优点的P-模糊-PID滑模控制系统,并将其应用于某温度被控对象。通过进行系统仿真并分析仿真结果,说明所设计的滑模控制系统具有较强的鲁棒性。

PID controller has difficulties in solving the control problems such as nonlinearity, complex system of time varying, and un-clear model. A P-fuzzy-PID sliding mode control system was designed with the advantages of PID and fuzzy control, and it was applied in a temperature controlled object. The system simulation and result analysis shows that the sliding mode control system has strong ro-bustness.
