Extrusion control system of LADRC tread based on CPSO optimization
In order to solve the problems of complex mechanism,excessive disturbance and difficult measure-ment of extrusion control system for rubber tread production,as well as the shortcomings of traditional PID con-trol,a linear active disturbance rejection controller(LADRC)optimized by chaotic particle swarm optimization(CPSO)is designed to achieve stable control of extrusion quantity for tread production.The mathematical mod-el of tread extrusion quantity is identified systematically by MATLAB software.The tread extrusion control sys-tem with LADRC and traditional PID control mode are established to verify the advantages of LADRC method through simulation comparison,and the influence of LADRC method on the system under different interference is studied.CPSO algorithm is introduced to optimize the setting of LADRC parameters,models with different LADRC parameters are simulated and compared to verify the advantages of CPSO algorithm parameter tuning,different disturbances are added to observe the effect of controller parameter changes on system response.The simulation results show that LADRC method can compensate the interference better than PID controller.With the addition of CPSO algorithm optimization,output response,speed of the system are enhanced,and the ad-justment time is shorter.Compared with the LADRC,the CPSO-LADRC has more obvious control effect on the stability and robustness of rubber tread production extrusion process.
