A New PID Controller for Nonlinear Networked Control Systems with Stochastic Time Delays
Intelligent Computation Technology and Automation（2012）
摘要
In this paper, a novel PID feedback control algorithm for nonlinear networked control systems with random delays is presented by a new performance index. The performance index is represented by both maximizing information potential of tracking error and minimizing the square of incremental control input. The information potential is estimated by Parzen windows and quadratic Gaussian kernels. The convergence in the mean square sense has been analysed for closed loop stochastic NCSs. Simulation results show the effectiveness of the proposed approach.
