一种量化因子改进型的模糊自适应PID控制算法
An Improved Fuzzy Adaptive PID Control Algorithm Based on Quantization Factor
摘要
Abstract
Aiming at the problem of dynamic performance under fuzzy PID control,a fuzzy-PID control algorithm based on improved quantitative factor is proposed.The online adjustment function of fuzzy domain quantization factor is introduced in the fuzzy quantization link to realize the real-time adjustment of fuzzy quantization factor.The dynamic performance comparison experiments of the traditional PID control,the traditional fuzzy PID control and the quantization factor improved fuzzy PID control are carried out under the unit step input signal at the system frequency of 100 kHz and 200 kHz,respectively.The results show that the algorithm can achieve no overshoot under two system frequencies,and the settling time is less than 0.15 s,and its dynamic performance is significantly improved compared with the traditional control algorithm.关键词
