摘要
针对经典PID控制参数整定困难和基本BP算法收敛速度慢、易陷入局部极小的缺点,提出一种基于线性预测模型BP神经网络的PID控制方法,重点阐述算法过程。最后在MATLAB软件上进行仿真,仿真结果表明该控制算法是有效的。
For the classic PID control parameters tuning difficulties and basic BP algorithm is slow convergence and easy to fall into local minimum of the shortcomings,this passage presents a linear prediction model based on BP neural network PID control method,focusing on the algorithm process.The programming steps under MATLAB are finally described.Simulation result shows that the control algorithm is effective.
