A Model-Reference Adaptive Motion Controller for a Differential-Drive Mobile Robot
نویسندگان
چکیده
This paper describes the design and implementation of a model-reference adaptive motion controller for a diflerential-drive mobile robot. This controller uses absolute position information to modify control parameters in real time to compensate for motion errors. Robot motion errors are classified into internal and external errors. Cross-coupling control method is used to compensate for the internal errors that can be detected by wheel encoders. The adaptive controller provides compensation for external errors. The adaptive controller is analyzed, and its stability and convergence are discussed. Experiments are conducted to evaluate the control system and the results show significant improvements over conventional controllers.

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...

In this paper, the path following controller of an omnidirectional mobile robot (OMR) has been extended in such a way that the forward velocity has been optimized and the actuator velocity constraints have been taken into account. Both have been attained through the proposed model predictive control (MPC) framework. The forward velocity has been included into the objective function, while the a...
