Description
Summary:The reaching law approach for discrete variable structure control system is studied in this paper. A new reaching law named variable rate reaching law to which the stability at the origin can be expected is proposed. The special feature of this new reaching law is that it is directly proportional to the norm of state vector and can result in a sector-shaped switching region. On the basis of the variable rate reaching law and the conventional reaching law, a new control strategy with satisfactory performance is formed. The new control strategy is applied to the design of an active power distribution controller for a power system. Simulation results show that the controller designed in this paper can improve dynamic performances of the parallel synchronous generators system effectively.
