Abstract
Along with the power electronics widely applied in the power systems, the control performance of power electronic system plays an important role in the modern power system. There are many advanced control methods devoted to improve the control performance such as fast dynamic response, small steady-state error, large stability margin, and so on. In this chapter, a comprehensive and systematic review of most advanced control methods is elaborated in the introduction. The advanced control methods are generally classified into two categories: linear controller and nonlinear controller, which are basically based on the characteristic of the controller and how to model the controlled plant. Furthermore, the control structure and working principle of these advanced controllers are expounded in detail. In order to give a more intuitive interpretation of these different control methods, the most widely used three-phase voltage source converter is given as an application to control the grid current or power. Finally, the performance comparison of these advanced control methods is conducted, which can help engineers to choose appropriate control methods according the specific application and various performance requirements.
