Robust PID Control for Robot Manipulators with Parametric Uncertainties
Abstract
Most of the industrial robots use a classical PIDtype
controller for positioning tasks. A main reason for this is its
effectiveness in regulation tasks, simple linear structure, and
easy implementation. Moreover, it is well known that the
robustness properties of a PID controller make it an excellent
choice for set point control of robot manipulators. In this paper,
a robust PID controller is designed in order to cope with
modeling uncertainties and unmodelled dynamics. First,
dynamic model of robot manipulator is derived using the
Rodriquez approach. Then, a PID controller is applied to
feedback linearized robotic system in order to suppress constant
disturbance and achieve good set-point control. The proposed
controller contains one adjustable parameter lamda , which has a
direct influence on the time constant of the closed loop system.
By adjusting it, one can accomplish a compromise between the
robustness and performance indices. Using this algorithm,
simulation res...ults of a NeuroArm robotic manipulator executing
positioning tasks are shown to demonstrate the efficiency of the
proposed controller.
