Adaptive control of continuous-time overmodeled plants

This paper presents an adaptive controller that will stabilize and asymptotically regulate any continuous-time, linear time-invariant plant, which has one input and one output. The only assumptions on the plant are observability, controllability and the a-priori knowledge of an upper bound on the plant order. The adaptive control concept combines continuous time state observation and sampled data control with a generalized, plant dependent hold function. The feedback gains and the hold function are adaptively tuned
