針對一般BP 算法存在的不足，提出一種改進(jìn)的BP 算法，并將其應(yīng)用于PID 控制器的參數(shù)設(shè)計中，并且克服了常規(guī)的PID 控制器參數(shù)整定的費時性，用MBP 算法的PID 控制器代替常規(guī)的PID 調(diào)解器。介紹了MBP 算法和基于MBP 算法的PID 控制器的控制結(jié)構(gòu)。通過仿真可以看到這種控制器的控制效果很好。還改善了系統(tǒng)的穩(wěn)定性。

Abstract: Aiming at the deficiency and limitation of BP arithmetic , a new BP arithmetic is proposed to design the parameter optimization of PID controller and overcomes consuming a lot of time in selecting .PID control parameters ,we take advantage of the PID controller based on the MBP arithmetic to replace the traditional one. It also introduces the arithmetic and the structure of PID controller of the MBP arithmetic. By way of the simulation, we see that the result shows that the stability is improved.
