Abstract

This paper presents a nonlinear adaptive backstepping algorithm for position control of an anthropomorphic robotic hand. The contraction force of PAM actuator has been modeled based on an empirical approach and the overall finger is represented as a nonlinear second order system, taking into account the system uncertainty caused by hysteresis phenomenon in PAM actuators. Adaptive backstepping controller has been developed by formulating the estimator of the system uncertainty. To improve the performance of controller, a cascade control system is developed by combining a conventional PID control, as an inner loop controller, with the adaptive back stepping position control as the outer loop of the controller. Finally, a simulation test is conducted to evaluate the performance of the proposed controller.
