An optimal strategy based on minimum effort control and also with terminal positionconstraint is developed for an exoatmospheric interceptor with a fixed- interval guidance time. It isthen integrated with sliding-mode control theory to drive an optimal sliding-mode guidance law forfixed-interval guidance time. In addition, this guidance law is generalized for intercepting anarbitrarily time-var...

Background: As a control strategy of industrial robots, sliding mode has the advantages fast response and simple physical implementation, but it still problems chattering low tracking accuracy caused by chattering. This paper proposes new for application robot control, which effectively solves these problems. Methods: In this paper, deep deterministic policy gradient–nonlinear nonsingular termi...

An improved non-singular fast terminal sliding mode control (INFTSMC) is proposed in this study, to improve the dynamic speed regulation and tracking accuracy of a surface-mounted permanent magnet synchronous motor (SPMSM) system. A surface that completely removes singularities from controller input proposed. The key characteristics INFTSMC are convergence errors, high accuracy, robustness agai...

In this paper, a nonsingular terminal sliding mode concept is introduced for the control of a class of nonlinear dynamical systems. This nonsingular terminal sliding mode control not only enables the £nite time convergence of the system equilibrium, but also eliminates the singularity problem associated with conventional terminal sliding mode control. Simulations are presented to show the effec...
