Robust stabilization by linear output delay feedback

The main result establishes that if a controller C (comprising of a linear feedback of the output and its derivatives) globally stabilizes a (nonlinear) plant P, then global stabilization of P can also be achieved by an output feedback controller C[h] where the output derivatives in C are replaced by...

l p Gain Bounds for Switched Adaptive Controllers

A class of discrete plants controlled by a switching adaptive strategy is considered, and lpbounds, 1 ≤ p ≤ ∞, are obtained for the closed loop gain relating input and output disturbances to internal signals.
