Abstract Details

2013, Master of Science, University of Akron, Electrical Engineering.
A novel speed control algorithm for permanent magnet synchronous motors (PMSM) which maximizes efficiency without requiring phase current sensors is proposed in this thesis. The algorithm is described for a buried magnet type interior permanent magnet (IPM) motor but it is also suitable for surface mount type motors. The suggested algorithm implements maximum torque per ampere (MTPA) control in a PMSM drive system, considering the parameter variations due to magnetic saturation and change in temperature. Only DC link current, DC bus voltage and mechanical speed are used in the implementation of the algorithm, eliminating the requirement for three phase current measurements. The scheme employs an online search algorithm with an initial condition computed from a-priori system information. Hybridization of the search algorithm with pre-computed control coefficients ensures robustness against parameter variations while maintaining good dynamic performance. The proposed scheme is implemented on a 1.5 HP IPM and the validity of the approach is justified through experimental and simulation results.
