The paper first instruct the infection of actuator hard failure in X rudder vehicle.

A stablizable method for uncertain linear systems with actuator failures;

This note addressed the problem of reliable guaranteed cost control system design for linear uncertain systems with circular pole constraints,when actuator failures had happened.

By means of LMI,the sufficient and necessary condition for robust fault-tolerant H∞ controller in existence was given so that the systems could keep asymptotically stable against actuator failures and satisfy disturbance attenuation index prescribed.

Study on LQR possessing integrality tolerant controller under condition of actuator fault;

Reliable pole placement of linear system considering actuator fault;

Robust actuator fault detection and reconstruction for a class of uncertain dynamic system with mismatched uncertainties;

After a research on the feedback and control of the reliable time-lag of continuous-time systems with actuator failures.

A more practical and general model of actuator failures is adopted.

?The reliable placement of disk pole with actuator failures is discussed for the constant linear system with uncertainty.

Robust Reliable H Control with Actuator Faults;

For a class of uncertain linear systems with uncertainties which donot satisfy matching condi- tions,the design method for reliable tracking controller against actuator faults is presented.

The problem of robust reliable tracking controller design against actuator faults for systems with polytopic type uncertainty is addressed based on the parameter-dependent Lyapunov function approach.
