Spiral elevator is a kind of servo system with load bearing function. Because of its electro-mechanical coupling properties and nonlinearity properties and too many of controller parameters, to adjust the parameters of the controller by artificial experience and other traditional methods are not only time-consuming, but also difficult to get better control performance. To solve the problem, the controller parameters of three-ring closed loop controller are optimized by using particle swarm optimization (PSO) algorithm. The simulation results indicate that the dynamic response characteristic, antigambling capability and robustness of the optimized system are improved.
