PID Parameter Tuning for Position Control System of Electro-hydraulic Servo Actuator Based on BWO Algorithm
A proportional integral derivative(PID)parameter tuning method based on the beluga whale optimization(BWO)algorithm was proposed,and the PID controller based on the BWO algorithm(BWO-PID)was designed.A mathematical model of the position control system of an active suspen-sion electro-hydraulic servo actuator was developed,and the simulation results were compared with the PID controller based on the Ziegler-Nichols algorithm in MATLAB/Simulink.The experimental results show that under the control of the BWO-PID,when the step signal was input,the tuning time of the sys-tem is reduced by 68.61%,and the response is fast without overshooting.When the sinusoidal signal was input,the system has stronger anti-interference and robustness.When the random road excitation was input,the maximum absolute value and root-mean-square value values of the actuator displace-ment response error are decreased by 54.16%and 53.85%,respectively.
