摘要：AbstractThis paper studies the problem of controlling a long distance transmission system for huge amounts of electrical energy (Generator-Load VSC-HVDC). An adaptive controller is designed to meet two controller objectives: (i) regulating the continuous voltage at the end of the HVDC cable; and (ii) ensuring a perfect power quality and system stability, which can be achieved by continuously adjusting the active and reactive powers independently. The controller's robustness is addressed by considering various parameter uncertainties, such as DC cable parameter variations. Furthermore, since the DC load is usually located at great distances from the control unit, a high gain observer is designed to estimate the DC cable states, as well the current in the load. Thus, the output voltage and current of the VSC are the only accessible measurements. The theoretical analysis results are approved by numerical simulation within MATLAB/SIMULINK environment.
