基于改进蜻蜓算法的磁齿轮复合电机控制研究
Research on control of magnetic gear compound motor based on improved dragonfly algorithm
摘要
Abstract
In order to solve the problem of oscillation and overshoot of double-rotor structure of magnetic gear compound motor in contactless transmission,a self-tuning vector control method for double-closed loop PI(proportional integral)parameters based on improved dragonfly algorithm(IDA)was proposed.Aiming at the shortcomings of DA in convergence speed and convergence accuracy,Tent mapping,improved weight coefficient and differential optimization algorithm were introduced in the early,middle and late stages of algorithm optimization respectively,and penalty terms that could suppress oscillation and overshoot were added to its fitness function,so that the convergence speed and convergence accuracy of the algorithm were significantly improved.Three control methods of PI,DA-PI and IDA-PI were used for the control simulation and experiment of magnetic gear compound motor.The results showed that the overshoot and steady state error of motor speed under IDA-PI control were the smallest,and the dynamic response speed was the fastest,which proved the effectiveness of the proposed strategy.The research results provide a reference for the control of magnetic gear compound motors with different topologies.关键词
