In this paper, an improved reconfiguration control scheme via an H ∞ fault observer and adaptive control is studied for the quad-rotor helicopter with actuator faults. The bilinear problem is eliminated by constructing fault compensation and control law reconfiguration in the adaptive controller. Fault estimation is achieved by designing the fault observer with an H ∞ performance index, which is applied to evaluate the 'locking in place' fault of the actuator in a quad-rotor helicopter. By drawing the H ∞ performance index into the adaptive fault observer, an asymptotically convergent estimated error can be attained and the burden of the adaptive controller is alleviated. Some simulation and experimental results confirm the availability of the reconfiguration control scheme.

In order to enhance the ability of thermal unit to participate in fault recovery under the large-scale wind power consumption and grid’s power loss, the power grid emergency optimization control method based on wind power and thermal power adjustable capacity is proposed. Based on the analysis of the influencing factors of wind power, considering the matching operating conditions of wind power output, the strategy of unit lockout control under grid over-frequency is proposed. According to the regional control error(ACE) of the power grid, one power emergency control method based on one-key climbing is constructed. The scheme can make full use of the thermal power unit load regulation space and short-term rapid adjustment rate to improve the grid’s ability to cope with large power loss and ensure grid frequency stability.
