Abstract :
A robotic application in which the control architecture is characterized by a computed torque scheme operating in conjunction with an input/output type of direct model reference adaptive controller has been developed. This control scheme, called the adaptive computed torque control scheme (ACTCS), aims to integrate the two philosophically different control strategies. The stability and robustness issues of the controller in response to a variety of input signals are examined. Experimental results on the Colorado State University (CSU) 3 degree-of-freedom cylindrical robot are presented
