Application of genetic algorithm for balancing control of hydraulic systems on specialized vehicles

Abstract

The PID controller is widely applied in control problems because of its simple structure and ability of working stable and reliable. In the problem of balancing control of the hydraulic system on a specialized vehicle, a PID controller can be used and determined by the Ziegler - Nichols method. With this controller the system can achieve a steady state, however the parameters of the PID controller need to continue to be calibrated to achieve the optimal values. In this paper, the authors present a method of applying a genetic algorithm in tuning the PID parameters. The simulation results show that the PID controller, after optimization by the genetic algorithm, gives better control quality. The solution presented in the article is applied to the SPU launcher vehicle and achieves good results.
