- The paper presents a comparative study of nonlinear control techniques for AC/DC line-side converter. Virtual Flux Based Direct Power Control for AC/DC converter has been modified by adding nonlinear DC-link controllers. In particular, design methods of robust control has been presented and used to design robust controllers: sliding-mode controller, fuzzy-logic controller and sliding-mode fuzzy controller. The sliding-mode method uses the concept of a sliding line which divides the state space into two semi-planes and defines the distance to the sliding line. Since the system trajectory reaches the sliding line, it cannot leave it. This is achieved despite parameters fluctuation and disturbances, being the main characteristic of robustness. Fuzzy logic controllers are designed by using the phase plane determined by error e and change of error e . The phase plane is next parted into two semi-planes by means of sliding line. This makes diagonal form of fuzzy logic control similar to sliding-mode with boundary layers. The goal of the control systems presented in the paper is to maintain the output dc-link voltage at the required level, while line currents should be ideally sinusoidal and in phase with respective phase voltages to satisfy the unity power factor (UPF) condition.
