针对自抗扰控制器参数难以整定的问题,提出了基于粒子群优化算法的自抗扰控制器优化设计方法。该设计方法的实质就是选择合适的适应度函数,利用粒子群优化方法对自抗扰控制器的可调参数进行优化。设计方法运算简单,易于实现。对某炮控伺服系统的仿真研究表明,这种方法是可行的。 Aiming at the difficulty in setting parameters of ADRC controller, an optimal design method of ADRC controller based on Particle Swarm Optimization (PSO) algorithm is proposed. The essence of the design method is to select the appropriate fitness function and optimize the adjustable parameters of the ADRC by using PSO. The design method is simple and easy to implement. Simulation of a gun control servo system shows that this method is feasible.
