Learning Outcomes
The student knows the principles of modern closed-loop motor drives and knows how to apply this knowledge in the parametering of the drive. In cage motor control, the student is introduced to the properties of scalar, vector and direct torque control. The student is familiar with cycloconverter controlled synchronous machines. The student is familiar with the reference value chain of speed and torque control in multi-motor drives.
Student's Workload
Total work load of the course: 107 h.
Contents
DC motor speed and current control, the transfer function of the control and the tuning of the controller. Cage motor control with scalar, vector and direct torque control. Synchronous motor control with cycloconverter, LCI drive and intermediate circuit frequency converter. Control of permanent magnet synchronous motor. EMC issues, bearing currents and overvoltages. In the laboratory sessions speed and torque controlled motor drives are parameterised and tested using various motor alternatives.
