How-ever, the discontinuous control signal causes a significant problem of chattering. In this paper, a new and simple approach to chattering free SMC methodology is proposed. The main purpose is to eliminate the chattering phenomenon.
WebJul 11, 2024 · Simulation results obtained by using the proposed chattering-free SMC are shown in Figures 3–5. To show the superiority of the proposed controller in chattering suppression, another controller is applied which is the classic reaching law based SMC proposed by Gao . The same compensation strategy is also used in this controller. WebSMC is an effective and robust technology for parameter variation and external disturbance rejection. It has been applied to robot and motor control [9–12]. SMC is a robust for nonlinear systems. Discontinuous systems require an infinite switching frequency. Therefore, reducing chattering is very important for SMC.
WebMay 1, 2024 · When compared to first order SMC, HOSMC provides smoother control, better performance in terms of switching delays in control implementation, eliminates the requirement of derivative information for the control and is better in chattering effects suppression while still preserving the main advantages of the conventional SMC … Webapproaches to reduce the chattering of SMC. For example, Kachroo and Tomizuka [4] used a boundary layer around the switching surface to eliminate chattering in the SMC. The novelty of designing sliding mode control depends on how to select sliding mode surface. In this research, three controllers that include robust sliding mode control (RSMC), new
