This paper develops a nonsingular terminal sliding mode controller (NTSMC) based on extended state observer (ESO) for buck converter subject to load disturbances and input voltage variations. First, novel modeling method is developed transform the matched mismatched caused by resistance variations into uniform total disturbance. Second, an ESO established estimate differential of output Third, ...

In this paper, an extended state observer (ESO)-based nonsingular fast terminal sliding mode (NFTSM) control method is proposed for the speed tracking system of permanent magnet synchronous motor (PMSM) in present unknown parameters and time-varying load. Firstly, three finite time convergence ESO (FTCESO) are employed to estimate lumped disturbances one loop two current loops, respectively, es...

This study is mainly focusing on the problem of spacecraft close-range proximity with obstacle avoidance in presence complex shape. A novel Gaussian mixture model–based nonsingular terminal sliding mode control (GMM-NTSMC) proposed. achieved by developing GMM-based potential function a switching surface NTSMC. It theoretically proved that closed-loop system globally stable. The main contributio...

Abstract Due to the bus characteristics of large quality, high center gravity and narrow wheelbase, research its yaw stability control (YSC) system has become focus in field vehicle dynamics. However, tire nonlinear mechanical properties effectiveness YSC are not considered carefully current research. In this paper, a novel adaptive nonsingular fast terminal sliding mode (ANFTSM) scheme for is ...

Image stabilization is important for snake robots to be used as mobile robots. In this paper, we propose an adaptive robust RBF neural network nonsingular terminal sliding mode control reduce swinging in the robot’s head while it being driven. To avoid complex dynamic problems and interference during driving, a 2-DOF system. We designed system based on control, which ensures fast response finit...
