Purpose of this dissertation is to explore control techniques of PMSM motors and the design of a complex solution of sensorless control across a wide range of speed and torque. The proposed solution supports industrial implementation of different types of end equipment which use a PMSM motor. The work covers a thorough analysis of position and speed estimation. The Control structure is based on field oriented control technique, processes estimated quantities, and optimizes motor conditions to achieve maximum efficiency, start-up torque, and speed. The work discusses how the solution complies with the latest IEC standards. Compliance with these standards requires adapting the sensorless control technique and field oriented control structure. The elimination of a rotor position sensor and a temperature sensor measuring winding temperature requires development of techniques in software for blocked rotor detection and overload detection. The proposed solutions, which have been granted US patents, are explained in this work and utilize the unique features of an NXP microcontroller optimized for motor control applications. The achieved results are demonstrated on real industrial applications.
