Abstract :
The paper discusses the modelling issues for a two link flexible robot arm. The exact dynamic model of the robot arm is derived, and approximate forms suitable for the analysis and control design are proposed. The approach used here to derive an approximate finite dimensional model of the flexible robot arm is based on the Ritz expansion method. Simulations and experimental tests have been carried out to validate the approximate dynamic model of the robot
