A Fast-Dynamic Response Control Strategy for Power Supply Unit of SAR Satellites

An Emergency power supply unit is of great importance to an electric pitch control system especially in MW turbines. Based on a basic parallel-series shift circuit, the paper proposes a novel topology of an emergency power supply unit consisting of ultracapacitors in electric pitch system. Capacitance configuration is obtained and the percentage of efficiency improvement using parallel-series circuit is calculated. Then a control strategy involving three operating modes is established and specific parameters are shown with a flow chart. Finally a simulation of an emergency power supply unit is established and the result confirms the theory.

Active Control Strategy

A new semi-active control strategy is developed to adjust the voltage/current of magnetorheological (MR) dampers to track the optimal/desired damping force by the Linear Quadratic Regulator (LQR) method. Integrated with the new strategy, a modified inverse dynamic model is proposed to evaluate the value of evolutionary variable based on the Bouc-Wen model of MR dampers. This new strategy is firstly applied to a one-story building under El-Centro earthquake, and it is further applied to the dynamic response control of a fixed jacket offshore platform. The results show that this new semi-active control strategy can achieve efficient vibration control.
