WebApr 22, 2024 · Though, the second-order sliding mode is appropriate to obtain chattering-free control and guarantees a finite-time reaching phase [ 24 ]. In Section 3.1, second-order sliding modes are briefly introduced, then, in Section 3.2, super-twisting controller that is one of attractive second-order sliding mode controllers will be presented. 3.1. Figure 1: Phase plane trajectory of a system being stabilized by a sliding mode controller. After the initial reaching phase, the system states "slides" along the line =. The particular = surface is chosen because it has desirable reduced-order dynamics when constrained to it. See more In control systems, sliding mode control (SMC) is a nonlinear control method that alters the dynamics of a nonlinear system by applying a discontinuous control signal (or more rigorously, a set-valued control signal) that forces … See more Figure 1 shows an example trajectory of a system under sliding mode control.

WebApr 1, 2024 · Reaching phase. The controller’s gain increases to a value confining the system’s trajectories inside some neighbourhood of a sliding set (NSS) in a finite reaching-time. (ii) Adaptive phase. Once in the NSS, the controller’s gain is updated at the reaching time to maintain the system’s trajectories following sliding dynamics.
