For example, requirements to post system capabilities have stimulated new projects in the computation of available transfer capability and the pricing of ancillary services such as reactive power support. A major project involves the development of a comprehensive simulation platform to visualize the key aspects of power system operations and provide the capability of analyzing a broad range of issues using interactive graphics. This area spans the range of power conversion from one volt supplies for advanced memories to 100 kW inverters for motor control. The major theme of research effort is to develop large-signal nonlinear tools for analysis, design, and control. Fundamental issues such as the effects of noise on pulse-width control loops have been explored.
Several projects address inverters and converters in support of electric vehicle projects.
Electric Machines Projects in this area include field orientation control methods for ac induction motors, nonlinear control theory, including feedback linearization and integrator backstepping, and observer techniques for high performance without expensive sensors. These projects examine the operating performance of new motor control alternatives. Methods include analytical studies, detailed simulation, and experimentation. The Power and Energy Systems Group is the department focal point for two College of Engineering Large Team Design Projects - the Solar Electric Vehicle and the Hybrid Electric Vehicle projects. Each of these teams has involved more than 150 undergraduates, assisted by graduate team leaders and faculty advisors.
