Arm Manipulator Position Control Based On Multi-Input Multi-Output PID Strategy

摘要

A robot manipulator is a multi-articulated mechanical system, in which each articulation is driven individually by an electric actuator. As the most used robot in industrial application, this system needs an efficient control strategy such as the classical PID control law by means of which each articulation is controlled independently. This kind of control presents a lot of inconvenient, such as error of each articulation isn't taken account into others. In this work we present a Multi Input Multi Output (MIMO) PID controller to ensure the articulation robot control strategy, the results obtained present satisfactory and shows clearly the efficiency of the present PID-MIMO controller.
