The original idea of the thesis was realized to control the electric drive of the rotor with a special feature. Without using a complex mechanism, the angle of each blade of the rotor can be controlled individually. The blades are fixed independently to a permanent magnet and the housing encompassing the rotor contains coils. By powering the coils, the whole rotor turns into a permanent magnet motor and by using a control algorithm, each blade can be separately driven. In the first chapter, the introduction to the main idea of the research project is described along with working principle of rotor blade. The basic concept of blade angle is introduced. The second chapter is the state of Technique. In this chapter, the working principle and basics of permanent magnet synchronous machine and brushless motor with mathematical model is described. Also, space vector pulse width modulation and double acting piezoelectric actuator model for helicopter rotor are explained. The third chapter is the overall description of the initial status of the research project. This part includes the basic principle of the control system, sensorless field-oriented control of Permanent Magnet Synchronous Machine (PMSM). Also, the motor parameters calculated from the python script of motor design are listed in tabular form. The fourth chapter focuses on control strategy implementation. First of all, the criteria for selecting the microcontroller are described. After that, the structure of the program with a flow chart was explained. Also, a short description is mentioned of how space vector pulse width modulation is applied. The main function of the position and speed controller with block diagram is explained. Moreover, back-EMF based observer and EKF-based observer are described. In the fourth chapter, the initial problem of the research project is discussed. To overcome this problem, a set of experiments is carried out. In the last chapter, the result of the experiment with proper explanation is summarized. Further on the future work to solve the problem is listed.
