Abstract : Control of motion systems involving distributed mechanical flexibility is studied using artificial neural networks. Infinite dimensional nature of the problem due to distributed flexibility, nonlinear dynamics of mechanical structural systems, and fault tolerant operation requirements are taken into consideration. Three different neuro controller architectures are studied: 1) Hopfield nets for modal parameter estimation and real time solution of LQ optimal control problem, 2) Feedforward nets using EKF learning algorithm as a fast learning, trainable nonlinear adaptive controller, 3) CMAC neural network controller for high precision motion control. Thre results are summarized and details are presented in refereed publications.
