This paper presents a robust adaptive ℋ∞ strategy to solve the attitude of the quad-rotor helicopter control problems with actuator failures and external disturbances. The dynamic motion equations are obtained by the Euler formalism. Based on the linear time-invariant state-space equations of the quad-rotor, a state feedback robust adaptive ℋ∞ tracking controller is proposed to track the given attitude...
This paper addresses the reliable synchronization problem for a general class of uncertain chaotic systems with adaptive mechanism. By combining adaptive method and linear matrix inequality (LMI) optimization technique, an adaptive reliable synchronization controller is established to guarantee synchronization between the master chaotic and slave chaotic systems even though actuator failures occur...
This paper deals with the problem of robust tracking control with adaptation mechanism to improve transient performance in time-response. A linear time-invariant system with time-varying ellipsoidal uncertainty is considered. The proposed controller affinely depends on the estimations of parameters, which are adjusted on-line according to the error between the state trajectory of the plant and that...
Ship anti-rolling tank test platform is an important equipment for the study of the anti-rolling tank and the accurate imitation of the ship moment in the sea waves, which plays a key role in the design of the ship anti-rolling test platform. In this paper, the electro-hydraulic servo system is employed to imitate the sea wave moment. Based on the comparison with the PID control and the adaptive control...
