✦ Synopsis

This paper deals with the problem of semi-globally stabilizing a linear system in the presence of input additive uncertainties and disturbance using actuators that have imperfect input output characteristics. The input output characteristics of the actuators used include those of dead zone and saturation and are not precisely known. Two design approaches, the low-and-high-gain approach and the low-gain-based variable structure control approach, are taken in solving the problem.

It is shown that, if a linear system is asymptotically null-controllable with bounded controls, then, when subject to both actuator position and rate saturation, it is semi-globally stabilizable by linear state feedback. If, in addition, the system is also detectable, then it is semi-global stabiliz

For a linear system under a given saturated linear feedback, we propose feedback laws that achieve semi-global stabilization on the null controllable region while preserving the performance of the original feedback law in a ΓΏxed region. Here by semi-global stabilization on the null controllable regi
