Abstract

To solve the parameter tunning problem of PID controllers in master-slave control structure of electro-hydraulic servo system, this paper proposed a solution method based on multi-objective optimization algorithm combined with model simulation. This method modeled the problem as a multi-objective optimization problem whose target space included four dimensions, namely master-slave synchronization error, settling time, overshoot and integral squared error. And it established the simulation model of master-slave PID control structure to obtain the target value of the target space. Additionally, it improved the MOEAD algorithm by strengthenning the diversity of generated offspring through the selection of parents along with the offspring generate operators and readjusting the weight vector through the substitution strategy of invalid ones using external populations and binding mechanism between weight vectors and individuals. Finally, this method got the final Pareto non-dominated solution set and then selected the knee point individual as the optimal parameter of the controller in the solution set, which improves the control quality of the master-slave synchronization structure.
