This paper presents a sliding mode control (SMC) design based on radial basis function neural network (RBFNN) to robust stabilization and disturbance rejection of the synchronous reluctance motor (SynRM) drive system. This method utilizes Lyapunov function and the steep descent rule to guarantee the convergence of the SynRM system asymptotically. Finally, we employ the experiments to validate the...
In this paper, a variable structure controller based on sliding-mode design is proposed for induction motors that propel electric vehicle drives. The underlying design concept is to endow the closed loop system with high performance dynamics for all possible speed ranges while maximizing power efficiency and keeping the required stator currents within the inverter ceiling limits. The proposed approach...
An robust control scheme on the model of surface permanent magnet synchronous motor, composing a sliding-mode controller and a sliding-mode observer, was presented in this paper. To eliminate the effects of parameters variation and uncertainties, the controller was constructed instead of conventional PI controller as well as the self-adaptive rule was deduced using Lyapunov stability theory. The required...
This paper focuses in the design of an adaptive sliding mode control (SMC) for induction motor drives, that reduces the high frequency chattering that usually appears in the SMC schemes. The proposed design consist of a sliding mode control law that incorporates an adaptive switching gain. This adaptive switching gain avoids the need of calculating an upper limit of the system uncertainties as it...
The design of a speed sensorless PWM robust control scheme for an induction motor drive in order to control the rotor speed is proposed. The proposed design is divided in two parts. In the first one it is designed a speed estimator to estimate the rotor speed. In the second one it is developed the proposed robust control. This robust control comprises two parts, the so called inverse dynamic technique...
This paper discusses the nonlinear control problem for variable-speed wind energy conversion system. Due to the stochastic operating conditions and the inevitable uncertainties inherent in the system, linear control method comes at the price of poor system performance and low reliability. So, it first develops a detailed model of variable-speed wind energy conversion system, which incorporated a distributed...
