基于PSODE混合算法优化的自抗扰控制器设计
Design of active disturbance rejection controller based on joint optimization algorithm of PSODE
摘要
Abstract
Since the active disturbance rejection controller in strong interference system and under large?delay condition has bad control effect due to the influence of the static parameter mechanism,an active disturbance rejection controller based on the joint optimization of the particle swarm optimization algorithm and difference evolution algorithm was designed. The particle swarm optimization algorithm is used to optimize the momentum estimation coefficient of the anti?expansion state observer in the controller online. The servo mechanism started by the error threshold trigger is adopted to improve the computation speed of the dynamic optimization. The mutation,crossover and selection operators of the difference evolution algorithm are employed to im?prove the diversity of the particle swarm optimization algorithm and prevent it from falling into the local optimum,so as to im?prove the convergence precision of the algorithm. The experimental results of the thermal time delay system show that the control effect of the improved controller in strong interference system and under large?delay condition is improved,and the anti?jamming performance and robustness are enhanced.关键词
