DC machines are prone to oscillations or swings in angular speed and armature current due to dynamic changes in the operating conditions, such as excitation and mechanical transients from load or speed variations. In this thesis, a sensitivity analysis-based parameter optimization is applied to a separately excited DC motor to mitigate the swings. A gradient-based criterion minimization method is employed to minimize the gradient of the performance index of the angular velocity and armature current. The optimization is performed on the modeled system and the optimal gain values are fed to the actual system for improved dynamic performance. The angular speed (o) and armature current (Ia)-based control approach converges faster reaching optimal gain values compared to the existing o only-based control approach. The effectiveness of the proposed approach is quantified by comparing the integral squared error of the performance index with that of the existing -based control approach. The proposed approach results in a smaller time constant and reduced oscillation damping time, and improves the response of both o and Ia. The approach promises an efficient swing mitigation in the actual physical system during excitation, speed variations and mechanical transients.
