Resolved acceleration and PID control provide high-performance control in an omnidirectional mobile robot, but most research does not consider plant parameter perturbations requiring that control gains be readjusted. We present an adaptive PI control strategy for mobile robots that automatically adjusts PI controller parameters based on error signals. Experiments verify the effectiveness of our method.
