中文摘要 | A third-order nonaffine, nonlinear high voltage direct current (HVDC) model was developed to supply constant rectifier DC current and inverter DC voltage in HVDC systems. The inverse system method for multivariable nonlinear control was used to design a nonaffine, nonlinear, two-input and two-output decoupling optimal controller using feedback linearization and linear quadratic regulator (LQR). The stability of the closed loop control system was analyzed to identity the necessary and sufficient conditions for zero-dynamic stability. The scheme improves the converter stability and prevents phase-transfer failure. Simulations verify the effectiveness of the method. |
