Nonlinear Adaptive Control of AC Electric Drives

Abstract

The use of energy dynamics/dissipative design is one unifying theme for the various projects carried under this grant, exploring the scope of quadratically dissipative design, design based on shaping Hamiltonian dynamics and design for systems with non-quadratic energy structures. Specific projects involved the permanent magnet synchronous, switch reluctance, induction and DC motors, power electronics devices, including a three phase synchronous rectifiers, the series resonant converter, voltage source inverters, and power distribution systems. Projects involving electric motors ranged from a basic dissipativity based controller, to modeling and adaptive attenuation of torque ripple, and observer based shaft sensorless control for dynamic speed tracking. Concepts of nonlinear dissipative control and observer design were also studied in a fluidic turbulent system that features nonquadratic non linearities and Hamiltonians.
