Hydromechatronics engineering is a complex system,and the control algorithm and parameter of control system directly influence the control quality of system.Aimed at the puzzle that the control effect of conventional PID controller is not as good as expected for the control system with nonlinearity and strong coupling,and it is very difficult to tune the parameters,this paper designed a sort of improved controller of human simulated intelligence based on the improved algorithm of PSO.By means of improved particle swarm optimization algorithm,this paper conducted the research on parameter tuning of controller,drew lessons from operation factor characteristic in genetic algorithm based on particle swarm optimization,and presented a sort of improved particle swarm optimization algorithm with genetic thought.Under the condition of Matlab environment,the simulation experiment has been conducted and the superiority of this improved algorithm has been validated.By using Simulink tool,two sorts of controller have been designed and the comparative simulations have been performed.The simulation results demonstrated that the designed human simulated intelligent controller have better control quality than other controllers and this controller is feasible.The research results show that the controller after parameter tuning can satisfy the demand of control quality in controlled system.
