This paper develops a global model of a two-stage grid-connected microinverter which uses sliding-mode control laws in both stages. In the study, it is considered that the microinverter is fed by a current source representing the photovoltaic module with a capacitor connected in parallel. The model of the DC-DC stage is obtained from the linearization of the ideal sliding dynamics of the converter...
This paper presents the analysis of the quadratic boost converter operating in sliding-mode control in order to obtain high DC-gain. This approach uses a indirect control of the output voltage based on the use of a sliding surface defined with the input inductor current. The control law is argued through a stability test. The proposed control was implemented in MATLAB simulations with a quadratic...
The underwater vehicle control has two problems to deal with: parametric uncertainty and unknown disturbance. Sliding Mode Control (SMC) effectively addresses these issues and is therefore a viable choice for controlling underwater vehicles. On the other hand, this method is known to be susceptible to chatter, which is a high frequency signal induced by the switching control. In this paper a new control...
This paper present a design methodology of sliding mode control of a class of linear saturated systems. The constraint of saturation is reported on the control vector. Firstly, we present the structure of saturation and the new formulation of the saturated state system. Secondly, the synthesis of the sliding surface is formulate as a problem of root clustering, which leads to the development of a...
