摘要：
Many modern control applications, including teleoperation and control over networks, create challenges to applying nonlinear controllers in the presence of long delays in the actuation or sensing path. I will present techniques for compensating such delays, with an emphasis on delays that are time-varying and state-dependent. In the presence of state-dependent delays, the challenge is not only that the overall state of the system (plant plus actuator dynamics) is infinite-dimensional and the delay is time-varying, but also that the horizon for compensating the delay is not known a priori and the delay rate becomes dependent on the input. I will present solutions to the problem of stabilization in the presence of state-dependent delays for general linear and nonlinear systems. For constant delays, I will introduce sampled-data nonlinear controllers that compensate delays of arbitrary length, under arbitrarily sparse sampling. Illustration will be provided through several examples, including stabilization of the nonholonomic unicycle.
