Abstract :
It is well known that an asymmetric cylinder fifth-order electrohydraulic servo system is a class of typical high-order one with nonlinearity, time-varying and gain asymmetric. Because dynamic performances of the servo system vary greatly with the variable load, conventional PID is very difficult to be used to reach the desired performance target. 20-SIM simulation software is a simulation tool based on bond graph theory, and it is very suitable for simulation of nonlinear systems. Based on the aforementioned characteristics, we set up a simulation model using 20-SIM simulation tool, and design an online self-learning single neuron PID control algorithm. Simulation results show that this single neuron PID control scheme is better than conventional PID control.
