Designing a Simple Indirect Vector Controlled Drive System in Simulink

In recent years, the need for alternative fueled vehicles has been highlighted by government and industry leaders. The emphasis has focused on hybrid/electric drive systems. In order to compete with current technology, these drives must be capable of operating under various load conditions as well as operating over a large speed range. Such performance requirements require motor control systems that must be capable of overcoming changes within the drive system: primarily motor parameter changes at high speed operation. While multiple control algorithms exist for electric drives, some offer more robust control than others. These algorithms range in cost and complexity.;The objective for this thesis is to develop a basic model of a drive system in MATLAB/Simulink, study various sizes of motors and their performance, and analyze and summarize the findings of the simulation. Various control strategies were examined with the best choices implemented in the simulation. Similar analysis was done with a few motor types. The resulting analysis was used to select the appropriate drive system and motor type for automotive applications. With the motor type selected, three test motors were studied with various ratings and characteristics to determine the robustness of the controller. The drive system responses examined include torque response (i.e. overshoot and risetime) and flux variation. Satisfactory operation using a simple indirect vector control scheme was verified for all three motors with a linear load torque speed curve.
