| Abstract: | The design of variable structure control(VSC) of discrete-time systems and their quality control of the dynamical processes are studied. Through the review of the previously estabished versions of reaching conditions briefly, the characteristic of quasi-sliding mode is studied in detail. On the basis of stability and simple form of control the conception of adaptive discrete reaching law is proposed. The periodic convergence law is given and the reaching-convergence method is built to design VSC, which solves the steady-state chattering and optimizes the movement quality of all processes. |
