摘要

In this paper a sliding mode control (SMC) technique is used for speed control of DC drive. Electrical Drives are used in modern industrial applications with the recent development in power electronics devices. The main feature of SMC is order reduction, decoupling design procedure, load disturbance reduction, and insensitivity to parameter variations (called robustness of system). Reduced order model for DC drive with measured speed and observed state is used. In SMC with unmodelled dynamics chattering phenomenon is eliminated by constructing the sliding manifold based on reduced order with observer state as better than reduced order with measured state. In case of high order models of electric machine, non-linear ties in motion equations; uncertainties in model parameters and disturbances are the main obstacles for development mathematical analysis of such systems. The simulation result depicts that reduced order with observer state is better than reduced order with measured state.
