This paper presents the usage of sliding mode Control algorithm for the load frequency control in power systems. A sliding mode based load frequency controller is applied to a two-area power system. Non-reheat and reheat Thermal turbines are distributed in these two areas respectively. The nonlinearities such as governor dead band and generation rate constraint are included in the block diagram...

Abstract. This work presents the design of robust sliding mode controllers for three-phase ac-ac matrix converters, in order to guarantee output sinusoidal waveforms and near unity input power factor. First, the sliding mode controller, based on the state-space vectors modulation technique, is designed for the matrix converter and the obtained results are compared to those obtained using the cl...

In this work, we propose a novel technique of higher order sliding mode control in order to solve the problem of chattering phenomenon which appears, generally, with standard sliding mode controller. The proposed approach provides an exponential stability on the sliding surface and guarantees the robustness of the closed loop system against uncertainties and external matched disturbances. The r...

in this paper, under the existence of system uncertainties, external disturbances, and input nonlinearity, global finite time synchronization between two identical attractors which belong to a class of second-order chaotic nonlinear gyros are achieved by considering a method of continuous smooth second-order sliding mode control (hoamsc). it is proved that the proposed controller is robust to m...

This paper is concerned with the development of a control system for rotational maneuver and vibration suppression of a flexible spacecraft. It is assumed that the system parameters are unknown. The design approach presented here treats the problem of spacecraft attitude control separately from the elastic vibration suppression problem. As a stepping stone, a state feedback sliding mode control...

This paper proposes a new method of sliding mode base controller for shunt active power filter to compensate the harmonic currents of a load. In this controller there isn't any need to PI DC voltage controller to regulate the DC capacitor voltage of shunt active power filter. In this method, first the reference currents of shunt active power filter that should be tracked to reduce or eliminate ...

Synchronization of coupled nonidentical fractional-order hyperchaotic systems is addressed by the active sliding mode method. By designing an active sliding mode controller and choosing proper control parameters, the master and slave systems are synchronized. Furthermore, synchronizing fractional-order hyperchaotic Lorenz system and fractional-order hyperchaotic Chen system is performed to show...

This paper proposes a new adaptive controller for the robust control of a grid-connected multi-DG microgrid (MG) with the main aim of output active power and reactive power regulation as well as busbar voltage regulation of DGs. In addition, this paper proposes a simple systematic method for the dynamic analysis including the shunt and series faults that are assumed to occur in the MG. The pres...

A generalized model-based sliding mode controller for robot trajectory tracking is proposed, which incorporates the full-order, nonlinear, uncertain actuator dynamics in control law design. The problem of chattering is alleviated by replacing the discontinuous sliding mode control in the vicinity of the sliding mode by a high gain, continuous controller, resulting in dual mode control. Independ...

In this paper, a sliding mode fuzzy controller for a nonholonomic wheeled mobile robot is proposed for tracking desired trajectories. We know that sliding mode control can deal with non linearities of control system and is robust. However, it has drawbacks such as a chattering. So, we introduce a fuzzy logic in order to reduce this phenomenon. Two sliding mode fuzzy controllers (SMFC) are descr...
