| Popis: | 89 In this dissertation, several issues are studied: digital redesign of continuous-time state-feedback controlled systems with input and/or state delays, digital modelling of continuous-time uncertain state-delayed/input-delayed systems, robust control of sampled-data uncertain state-delayed systems using digitally redesigned state-feedback controllers, and robust control of sampled-data uncertain input-delayed systems using digitally redesigned observer-based controllers. Based on the Law of Mean from the integral calculus, we derive the new digitally redesigned controllers from available analog controllers. Using the new digitally redesigned controllers, the resulting states of digitally controlled sampled-data time-delayed systems are able to closely match those of original analogously controlled continuous-time time-delayed systems. Moreover, we construct the digital uncertain models of continuous-time uncertain state-delayed and input-delayed systems by using the trapezoidal-rule approximation method and the Chebyshev quadrature method, respectively. The proposed new approaches are effective for designing the digital controllers of sampled-data time-delayed systems. Furthermore, the developed discrete-time uncertain time-delayed models are also helpful for digital simulation, analysis and design of continuous-time uncertain state-delayed/input-delayed systems. |
