Hypertracking and Hyperrejection: Control of Signals beyond the Nyquist Frequency
Kaoru Yamamoto, Yutaka Yamamoto, Masaaki Nagahara
This paper studies the problem of signal tracking and disturbance rejection for sampled-data control systems, where the pertinent signals can reside beyond the so-called Nyquist fr…
Stabilization of discrete-time piecewise affine systems with quantized signals
Masashi Wakaiki, Yutaka Yamamoto
This paper studies quantized control for discrete-time piecewise affine systems. For given stabilizing feedback controllers, we propose an encoding strategy for local stability. If…
