Advanced Control Method for DC Motor Drives

In this research work, trajectory tracking of DC motor is established. A hierarchical controller with the dc motor based on differential flatness and the dc/dc Buck converter is designed. In dc motor, angular velocity tracked from a desired velocity trajectory from the desired voltage profile. The inner current loop and the outer voltage loop of cascade control is modelled. The desired angular velocity trajectory is well tracked and the controller is robust in such dynamic operating conditions. The actual value follows the trajectory with time delay and reduced magnitude in simulation. So controller gains are introduced to overcome these issues. Along with that, hardware is to be implemented for the simulation model of overall system. It is important that these types of abrupt variations do not happen in practice at the same time, or with such large variations regarding their nominal values.
