In this webinar, you will learn how to use simulation to design and implement multivariable controllers for a four-joint robot arm. We use two different techniques that go beyond the traditional tuning of individual PID controllers. The first method shows automatic tuning of four coupled PID controllers simultaneously. The second approach demonstrates the design of a model predictive controller (MPC) that uses an internal model of the robot arm to forecast future plant behavior and adjust control actions accordingly.
After we develop the two controllers, we test and verify their performance. The controllers first are verified against the nonlinear robot arm model using desktop simulation. Then, automatic code generation is used to implement the controllers in C code. Finally, we complete the design validation by controlling a robot arm in real time.
