Abstract : A controller synthesis technique for a class of model reference systems is developed. Each system is composed of a single-input single-output nonlinear plant with input differentiations and a reference model of order lower than that of the plant. The plant parameters are unknown, except for the fact that they are bounded within known bounds. The technique is systematic and does not require the explicit identification of the unknown parameters. The resulting controller has a simple structure which is implemented by a feedback of only the system error and its lower-order derivatives. The controller ensures fast convergence of a norm of the system error vector to an arbitrarily specified ultimate bound with a guaranteed overall system stability. The final implementation of the controller requires that a simulation of the system be made. (Author)
