- Offered for Year: 2022/23
- Module Leader(s): Dr Shafiq Odhano
- Owning School: Engineering
- Teaching Location: Newcastle City Campus
Semesters
| Semester 2 Credit Value: | 10 |
| ECTS Credits: | 5.0 |
Aims
The module aims to enhance the students’ knowledge of the fundamentals of electric drive systems and their applications and to show the relationship between the theoretical and practical aspects of the subject. On successful completion, the students will be able to implement and analyse the control of a basic electric drive and apply various control concepts.
Outline Of Syllabus
Basic drive configurations and load characteristics; motor-load coupling; two and four quadrant operation; dynamic braking and regeneration; constant torque and field weakening strategies; examples for high bandwidth torque requirements; control basics applied to drives – performance metrics, first and second order feedback control systems
DC drives: dc motor modelling; state space models; use of H-bridge for variable supply voltage; modelling of a converter; current ripple; electrical and mechanical system transfer functions; armature current and rotor speed control; cascade control structures; digital control basics; position measuring devices; tuning methods for proportional-integral controllers for drives; additive disturbance rejection and steady-state error
AC drives: configurations of three-phase power electronic converter; space vector theory; three-phase to two-phase transformation; PM machine dynamic equations; reference frame transformation; vector control of permanent magnet synchronous motor; dynamic model of an induction motor; rotor flux-oriented vector control of induction motor drives; decoupled flux and torque control; torque control at high dynamics; voltage space vector generation through a three-phase power electronic converter; mathematical basis for space vector modulation; centre-aligned PWM modulation strategy; phase duty cycle calculations
Case Study: Study of a 24V digitally controlled drive system. Electronics design and control software issues.
