Abstract :
Nonlinear dynamic block oriented systems of Hammerstein and Wiener type are identified. Hammerstein system consists of a memoryless nonlinearity followed by a dynamic, linear system, while Wiener system is a cascade of a linear dynamic system connected to a memoryless nonlinearity. The class of nonlinearities considered is large and nonparametric. Identification algorithms based on input-output observations are proposed for both systems and their convergence and rates are studied. Simulation results are provided and possible applications of block oriented systems in robotics are discussed
