Chattering in smc
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. WebThe first solution for the second issue is that BSC is typically combined with the first-order sliding mode control (SMC) by utilizing the robustness property of SMC. However, there is a chattering disadvantage of the first order SMC [35,36,37,38].

WebThe SMC method cannot adjust the switching gain in real time. It is very sensitive to changes, leading to multiple mutations. Although there is still a small amount of the chattering phenomenon of the additional yaw moment when the AFSMC method is adopted, the chattering amplitude is significantly reduced.
