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...

This article proposes a generalized block control principle. The algorithm, developed in the framework of sliding mode control, offers insensitivity to parameter variations and external disturbances and simplification of the control design. In contrast to the known Block Control Principle, decomposing of the system into blocks where the dimension of state and control input coincide is not requi...

This paper proposes a particle swarm optimization algorithm tuned fuzzy terminal sliding mode control for the application of UPS inverters. Though classic sliding mode control (SMC) is insensitive to system uncertainties, it possesses an infinite system-state convergence time. For high-accuracy tracking control, a terminal sliding mode control (TSMC) is developed to provide a finite system-stat...

Absrrucr In this paper, a new fuzzy sliding mode control scheme is proposed for second-order linear timevarying systems in order to obtain faster error convergence and desired error dynamics. It is well known that a second-order linear time-varying system can be used to model higher order linear time invariant systems piece-wisely. Therefore, it is necessary to do deep investigation for the sta...

Aiming at a class of multiple-input multiple-output (MIMO) system with uncertainty, a sliding mode control algorithm based on neural network disturbance observer is designed and applied to ship yaw and roll joint stabilization. The nonlinear disturbance observer is finished by radial basis function neural network and with that a terminal sliding mode control algorithm is proposed. The asymptoti...

This paper presents a trajectory tracking control method for nonholonomic mobile robot which is based only on kinematic model. A mobile robot trajectory tracking control method, based on terminal sliding mode control, with asymptotic stability is presented. Based on kinematic model of mobile robot, a terminal sliding mode control law for the angular velocity is proposed to reduce the tracking e...

Sliding mode control (SMC) has been a very popular technology due to its simplicity and robustness against uncertainties disturbances since inception more than 60 years ago. Its foundation of stability stabilization is built on the principle Lyapunov theory which ascertains asymptotic stability. In 1990s, novel class SMC, called terminal sliding (TSMC), was proposed studied applied extensively,...

in this paper a mesh-free model of the functionally graded material (fgm) plate is presented.  the piezoelectric material as a sensor and actuator has been distributed on the top and bottom of the plate, respectively. the formulation of the problem is based on the classical laminated plate theory (clpt) and the principle of virtual displacements. moreover, the particle swarm optimization (pso) ...

The camera stabilizer stabilizes the camera’s line of sight by isolating the camera from the model uncertainties, disturbances of operating environment and system movements. This paper presents a voltage-base optimal adaptive fuzzy sliding mode control for camera stabilizer. In this proposed control method, a voltage-base sliding mode controller is applied. But unfortunately, undesirable ...
