基于仿人智能积分的Fuzzy-PD控制器性能优化研究

Performance Optimization Research of Fuzzy-PD Control System Based on Human-simulated Intelligence Integral

针对常规PID控制器的积分控制难以兼顾系统稳定性与精确性的矛盾,采用仿人智能积分与Fuzzy-PD控制相结合的复合控制策略,在提高系统快速性的同时减少了超调量并保证了精确性.仿真结果表明了控制策略的有效性,达到了控制器性能的全面优化,解决了常规PID对非线性、时变、模型未知等复杂对象难以实现有效控制的问题.

In view of the integral control in conventional PID controller,which can not make a compromise between the stability and accuracy of the system,a mixed control strategy composed with Fuzzy-PD control and human-simulated intelligence integral is adopted in this paper. This method improves the quickness of the system. It reduces the overshoot and enhances the accuracy of the system at the same time. The results of simulation show that the control strategy is effective, and the control performance is optimized. It is difficult for PID to have effective control over nonlinear or time-varying or model-unknown object. It provides a basis for engineering application.
