Load Frequency Control for Power Systems with Actuator Faults within a Finite-Time Interval.

This paper is concerned with the issue of finite-time H ∞ load frequency control for power systems with actuator faults. Concerning various disturbances, the actuator fault is modeled by a homogeneous Markov chain. The aperiodic sampling data controller is designed to alleviate the conservatism of attained results. Based on a new piecewise Lyapunov functional, some novel sufficient criteria are established, and the resulting power system is stochastic finite-time bounded. Finally, a single-area power system is adjusted to verify the effectiveness of the attained results. [ABSTRACT FROM AUTHOR]
