Abstract

The new robust reaching law based sliding mode control is used for chattering suppression, minimization of steady state error and reaching speed kept minimsed. Here saturation function is used instead of signup function. With fine tuning of parameters of reaching law, the sliding mode reaches the equilibrium point at the earliest. The immovability of the proposed reaching law is analyzed with Lyapunov stability. In one hand, they promise the system attain the sliding surface quickly and stay on it, in another way they decline the chattering successfully, even unmatched certainties’ and disturbances. Such that the scheme reply can better realize the unification of rapidity. The robust reaching law is compared with traditional reaching law. A proposed reaching law applied to SMC DC-DC buck converter to reduce chattering, because switching devices exist in the model, it reduces the switching losses in the switching devices of the dc-dc converter. In turns efficiency of the buck converter increases. MATLAB Simulation results gives significant reduction of chattering by robust reaching law compared to constant plus proportional pace reaching law and very less sensitive on line and load variation Feature work of this article be to apply solar power stations.
