Robust stability analysis of Inverse LQ regulator for linear systems with input delay

چکیده
S AbstractWe analyze the robust stability of Inverse LQ regulators for single-input linear systems with uncertain input delay. Unlike the usual LQ regulator, the Inverse LQ regulator has a gain tuning parameter that can be chosen freely to some extent without losing its LQ optimality. Utilizing this freedom we seek the range of tuning parameter that ensures the robust stability against the uncertain delay time, as well as the robust stability condition of the Inverse LQ regulator for some gain tuning parameter. The result is based on the quadratic stabilization problem.
