针对一般BP 算法存在的不足,提出一种改进的BP 算法,并将其应用于PID 控制器的参数设计中,并且克服了常规的PID 控制器参数整定的费时性,用MBP 算法的PID 控制器代替常规的PID 调解器。介绍了MBP 算法和基于MBP 算法的PID 控制器的控制结构。通过仿真可以看到这种控制器的控制效果很好。还改善了系统的稳定性。 关键词:PID 控制器;BP 算法;MBP 算法;参数整定 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.
