Abstract:

Abstract POLAR FIELD-ORIENTED CONTROL with 3RD HARMONIC INJECTION Martin Todd Hess Field Oriented Control (FOC), also known as vector control, is a widely used and well documented method for controlling Permanent-Magnet Synchronous Motors (PMSM) and induction motors. Almost invariably the orientation of the stator and rotor (field) fluxes are described in rectangular coordinates. In this thesis we explore the practicality of using polar coordinates. Third harmonic injection is also a well-known technique that allows full utilization of the bus (DC-link), thus allowing the motor to run to ful

Abstract:

Field oriented control is an established technique for rapid control of torque in induction motors. The controller tracks the orientation of the rotor flux, which rotates at synchronous frequency. The component of stator current in phase with this flux (known as the "flux current"), can be used to maintain a constant flux. Under these conditions, torque is directly proportional to the quadrature component of stator current, or "torque current". It has not proved cost-effective to measure either the rotor flux orientation or the motor torque directly. However both can be estimated from a combin

Abstract:

This thesis is about the development and performance enhancement of an induction motor electric vehicle drive system. The fundamental operation of the induction motor drive hardware and control software are introduced, and the different modulation techniques tested are described. A software simulation package is developed to assist in the control design and analysis of the drive system. Next, to establish the efficiency gains obtained by using space vector modulation in the improved drive system, an inverter with hysteresis current control is compared to the same inverter with space vector
