WebSep 1, 2024 · The commonly used reaching law forms include exponential approach law, power approach law, fast power approach law and double power approach law [13], [14]. In order to improve the dynamic quality of sliding mode approach motion, some improved reaching laws have emerged [15], [16], [17]. WebThe proportional and integral switching surface is constructed for each area to improve system dynamic performance in reaching intervals. The robust controller is proposed by the reaching law method to assure that frequency fluctuation converges to zero after a load and operation point variation.

WebAug 1, 2024 · This method is called the reaching law method. Gao and Hung proposed three different reaching law methods, viz., constant reaching law method, constant plus proportional reaching law method and power rate reaching law method. These methods have been then widely used by many researchers for various practical applications [12], [13]. WebAmong the DSMC design methods, the reaching law method [9, 10] has been demonstrated to be a simple and effective one. In this method, the desired evolution of the switching function is firstly defined, and then, a controller, which guarantees that the function varies in accordance with the definition is designed.
