摘要：

In this paper, a robust non-linear controller for a two-area voltage source converter high voltage DC (VSC-HVDC) transmission system is proposed subject to model uncertainties and external disturbances. The non-linear controller uses a robust feedback linearisation control for the voltage source pulse-width modulation (PWM) converter and inverter system of the DC-link along with a linear H∞ control strategy. The purpose of the converter control is to ensure independent control of the active and reactive power flow in the system while maintaining a constant DC voltage at the same time. For achieving robust feedback linearisation unlike the classical one requires the control of the square of the DC voltage rather than the DC voltage itself. This control strategy may provide the insight for the design of input-output linearised system, in which zero dynamics contain some desirable state variables. The controlled PWM has the global stability, fast tracking of DC bus voltage with zero steady-state error, rejection of exogenous disturbances, and stabilisation of synchronous generators connected to the VSC-HVDC systems at the two ends. © Institution of Engineers Australia, 2012.
