A Novel Pid-like Neural Network Controller
نویسندگان
چکیده
In this paper, a novel PID-like neural network controller (PIDNNC) is created. It is composed of a neural network with no more than 3 neural nodes in hidden layer, and there are an activation feedback and (or) an output feedback in hidden layer, respectively. This special structure makes the network be able to be a P, PI, PD, or PID controller as needed. The proposed controller weights can be updated on-line according to errors caused by non-linear and uncertain factors of system, based on some adaptation mechanism. The resilient back-propagation algorithm with sign instead of the gradient is used to derive the rule of updating network weights. The basic ideas, techniques and analysis are presented. Finally, we give the simulation experiment of a double inverted-pendulum system and the comparison of the effects between the proposed control strategy and the conventional one. Copyright © 2005 IFAC

This paper addresses a novel control method adapted with varying time delay to improve NCS performance. A well-known challenge with NCSs is the stochastic time delay. Conventional controllers such as PID type controllers which are just tuned with a constant time delay could not be a solution for these systems. Fuzzy logic controllers due to their nonlinear characteristic which is compatible wit...
