| 摘 要： | 针对一类非线性多变量离散时间动态系统,提出了基于神经网络的非线性多变量PID解耦控制方法。该控制器是由常规PID控制器与解耦补偿器、未建模动态前馈补偿器组成,而PID参数的整定是通过广义预测的方法实现的。同时给出了该控制方法的闭环系统的稳定性和收敛性分析。最后通过仿真实例验证了所提方法的有效性和可行性。

| Abstract: | An intelligent decoupling PID control approach based on neural networks was proposed for a class of uncertain nonlinear multivariable discrete time dynamical systems.The control system is based on the integration of conventional PID controllers,a decoupling compensator and a neural feedforward compensator for the unmodeled dynamics.The parameters of such controller are determined by generalized predictive control law.Stability and convergence analysis of the closed-loop system were given.Finally,simulation ... |
