This document deals with a sensorless field oriented control (FOC) for permanent magnet synchronous motor (PMSM) drives by using a full order sliding mode observer (FOSMO). We have constructed a FO-SMO to estimate the position and velocity. The Lyapunov theorem is used to verify the FO-SMO stability. The experimental findings indicate the robustness of SM observer under parametric variations.
In this document, an sensorless field oriented control (FOC) for PMSM utilizing the SMO is proposed. We have building a new sliding mode observer to estimate the rotor velocity/position from the back EMF, in which a continuous function (called sigmoid) is applied instead the sign method. The stability verification of our observer was made by the Lyapunov theorem. The effectiveness of sensorless FOC...
In this paper, an Adaptive Type-2 Fuzzy Sliding Mode Control is designed for a class of nonlinear Multi-Input Multi-Output (MIMO) systems with unknown partially dynamics and in presence of external disturbances. To estimate the unknown functions, a Sliding Mode Control (SMC) combined with Type-2 Fuzzy Logic are developed. The discontinuous term of the classical sliding mode law is substituted with...
In this paper, the main results are focused on the design of a robust tracking controller for a class of nonlinear Multi Input Multi Output (MIMO) systems involving uncertainties and external disturbances. A hybrid adaptive robust tracking control scheme which is based upon a combination of sliding mode technique, Proportional Integral (PI) controller and fuzzy control design is developed. Based on...
In this paper, a stable adaptive fuzzy sliding mode based tracking control is developed for a class of non-square nonlinear systems that are represented by input output models involving system uncertainties and external disturbances. The main contribution of the proposed method is that non-square systems are be controlled in their original non-square form instead of squaring them by adding or eliminating...
A stable adaptive fuzzy control based tracking control is developed for a class of Multi Input Multi Output (MIMO) non square nonlinear systems with external disturbances using sliding mode algorithm. This control algorithm further justifies that non square systems can be controlled in their original non square form instead of squaring them by adding or eliminating variables. This method integrates...
