Abstract: The lecture will describe the procedure from the modeling and simulation of the static and dynamic behavior to the designing of the adaptive controller applied on the nonlinear system. Knowledge about the static and dynamic properties is a necessary condition for design of a controller. One possibility how to obtain such information about the system is the investigation of the real system. Unfortunately, measurements on the real system are not always feasible. The only way how to obtain static and dynamic behaviour of these systems is the use of simulation, i.e. experiments on their mathematical model. Simulations have several advantages over experiments on the real system. Among them are the lower costs, increased safety and less time consumption. The adaptive approach here is based on external linear model (ELM) of the originally nonlinear system. The parameters of this model are identified recursively and controller parameters are recomputed in each step. Polynomial, pole-placement and Linear-Quadratic (LQ) approaches are employed for controller synthesis. All results come from simulations but they could be easily used for controlling of similar real nonlinear processes.
