Summary of Content:
This module addresses the control of AC drives and consists of a lecture component (10 credits) and a design and assessment project (10 credits)
The lecture component covers vector controlled induction motor drives and permanent magnet motor drives. Vector control is covered in depth covering the concept of space vectors, dq representation of 3-phase machines, dynamic equation structure and the concepts of direct and indirect flux orientation. Implementation of Indirect Vector Control, including current flux and speed control is covered in some detail and includes the effect of incorrect parameters.
Both AC and Brushless DC permanent magnet motor drives are introduced. The vector control concepts learned for induction machines are applied to AC PM machines. The concept of salient and non-salient AC PM machines are covered leading to the vector control using maximum torque per amp control strategies. Finally the field weakening control of both non-salient and salient PM machines are considered.
The project component is a design and simulation exercise using MATLAB/Simulink. The student is required to design an indirect vector controlled induction motor drive, implement the design in Simulink, and undertake evaluative tests covering current and speed loop performance, including field weakening for high speed. The exercise covers investigating the effects of parameter variation and designing engineered solutions to reducing the sensitivity.
