This paper presents a power compensation strategy to suppress the double frequency power ripples of Voltage source converter high-voltage direct current (VSC-HVDC) systems under unbalanced grid voltage conditions. The mathematical control equations of the double frequency ripple power of VSC under unbalanced operating conditions are firstly derived and established, where the dynamic behaviors of the double frequency ripples in active and reactive power are regarded as being driven by current-relevant components and voltage-relevant components, respectively. Based on the equations, a power compensation control strategy of VSC-HVDC is proposed via the passivity-based control with disturbance observer to suppress both the current-relevant and voltage-relevant components in the power ripples. With this control strategy, the double frequency ripples in active and reactive power are suppressed simultaneously and system performance is significantly enhanced with the implementation of the disturbance observer in the passivity-based control. Theoretical stability analysis and simulation cases show the effectiveness and superiority of the proposed strategy.

EPS can improve many aspects including chassis coordinated control. Aimed at eliminating the adverse effects deriving from the controlled and uncontrollable differential braking condition, this paper analyzed the EPS-based compensation system control strategy. Coordinated control of EPS and differential braking ensures the vehicle driving safety and driving comfort purposes. Based on the above research, this paper verified the EPS compensation control strategy in simulation environment.

New Strategy

The fuel-film evaporation model and transient fuel-film compensator model were established. By virtue of Simulink, the validity of above models were verified. The square wave perturbation method was introduced. Basing numerous calibration, the fuel-film compensation strategy including zoned compensation and damping factors ware proposed. This new strategy can compensate in-cylinder fuel fluctuation effectively during transient conditions.
