This paper concerns the problem of output feedback tracking (OFT) control with bounded torque inputs of robot manipulators,
and proposes a novel saturated OFT controller based on fuzzy self-tuning proportional and derivative (PD) gains. First, aiming
to accomplish the whole closed-loop control with only position measurements, a linear filter is involved to generate a pseudo
velocity error signal. Second, different from previous strategies, the arctangent function with error-gain is applied to ensure
the boundedness of the torque control input, and an explicit system stability proof is made by using the theory of singularly
perturbed systems. Moreover, a fuzzy self-tuning PD regulator, which guarantees the continuous stability of the overall closed-loop
system, is added to obtain an adaptive performance in tackling the disturbances during tracking control. Simulation showed
that the proposed controller gains more satisfactory tracking results than the others, with a better dynamic response performance
and stronger anti-disturbance capability. |
