This dissertation proposes 3 novel control methods for permanent magnet synchronous generators (PMSGs) used in wind turbines: **Part 1: Maximum Power Point Tracking (MPPT) at Unity Power Factor (UPF):** * Four control techniques achieve MPPT-UPF operation up to full power and speed, unlike previous methods. * The first uses constrained load angle control. * The next three use linear control systems: * Second: Linear relationship between load angle and reference speed. * Third: Non-linear load angle with reference speed, but linear relationship between generator current and optimum torque. * Fourth: Linear load angle with reference torque. **Part 2: Zero DC Current (ZDC) and Constant Field Link (CFL) Control:** * Two other PMSG control strategies (ZDC and CFL) are implemented using the new load angle control technique. * MPPT-based Load Angle Control (LAC) is achieved for both CFL and ZDC. * Each strategy has its own load angle control concept. **Part 3: Concurrent UPF-CFL Control:** * A novel combined UPF-CFL control method is proposed, integrating the best aspects of both individual techniques while maintaining UPF over the entire speed range. **Key benefits:** * All methods are simple and easy to implement in modern Digital Signal Processor control systems. * A unified phasor diagram simplifies understanding of each control technique. * MATLAB Simulink simulations validate the effectiveness of each proposed method. **Overall, this dissertation presents three innovative control methods for PMSGs that improve wind turbine performance and efficiency.**
