Abstract

The project aims in modeling and controlling of DC motor, using singular perturbation method in the presence of unknown disturbance, parameter variations and other uncertainties. A basic problem in control system theory is the mathematical modeling of a physical system. Typical control tasks are optimal regulation, tracking and guidance. Since these tasks are to be accomplished in the inevitable presence of unknown disturbance, parameter variations and other uncertainties, the control system must posses a sufficient degree of robustness or insensitivity to the extraneous effects. Singular perturbation method responds to this challenge. The key contribution is the simplification of dynamic models. One of them is to neglect ‘small’ time constants, masses, moment of inertia, resistance, inductance and capacitance, which increases the order of the system. However, a design based on a simplified model may result in a system far away from its desired performance or even in an unstable system. This problem is overcome by treating simplified design as a first step, then capture fast phenomena and slow phenomena at the second step. The separation of the time scales eliminates stiffness difficulties and prepares for a more efficient hardware and software implementation of the controller and also the overall performance of the system is improved. The project is implemented in MATLAB. MATLAB is selected because it is an effective tool for simulation.
