摘要
针对传统的PID神经网络(PIDNN)应用范围受限及积分误差规则难以获取的问题。为实现对非线性多变量系统的有效控制,拓展神经网络控制系统的应用范围,提出了基于改进型粒子群算法在PID神经网络控制系统设计中的解决方案,取代了传统的BP反向传播算法。仿真结果表明,与传统的PIDNN相比,系统的稳定性、鲁棒性及精确性都有了明显的提高,该方法有效的提高了PIDNN控制的使用范围,为智能方法在PID控制中的应用提出了一个新的参考。
The traditional PID neural network （PIDNN-） limited the scope of application and integration problems are difficult to obtain the error rule. For the realization of nonlinear multivariable control systems, neural network control system to expand the application range of this paper, based on improved version particle swarm optimization algorithm for PID neural network control system design solution, replacing the traditional BP back the propagation algorithm, simulation results show that compared with traditional PIDNN, the steady-state system, robustness and accuracy have improved obviously, this method is effective to improve the use of PID control, intelligent method for the PID Control proposed a new reference.
