A novel adaptive control of elevator motion system

This paper discusses the design of the elevator vertical motion control system. The requirements on elevator motion control are the comfort, the precise relevelling and the realization of shortest flight time. Starting jerks, parameter variation and disturbances cause an uncomfortable run. Considering these problems mentioned above, an adaptive controller is proposed in this paper. In the adaptive controller, an observer and a disturbance rejection control are designed. Besides this, the parameters of the linearized system are identified, thus allowing the observer coefficients and the gain values to be adapted, hence the effects of parameter variation and uncertainty can be reduced. The simulations of the proposed adaptive controllers s are made. The results show that the robustness of the adaptive controller is superior, and the convergence of the adaptive controller is better.
