Plant-Variable-Optimal Robust Servo System with Two Degrees of Freedom

Robust servo-system based on two-degree-of-freedom control with sliding mode

A robust servo-system, based on a combination of linear robust control and sliding mode control have been proposed. This new control system can be said to be a nonlinear system (sliding mode control system) which has a inner loop of linear control (two-degree-of-freedom control). Due to this inner loop of linear control, a disturbance is strongly suppressed but not completely. Then, the outer l...

Robust Tracking Control of Two-degrees-of-freedom Mobile Robots

A robust tracking controller for a mobile robot with two degrees of freedom has been developed. It is implemented and tested on a real mobile robot. Where other controllers show decreasing performance for low reference velocities, the performance of this controller depends only on the geometry of the reference trajectory. This allows accurate positioning at low speeds, close to obstacles. The d...

Control of Mechanical Systems with Variable Degrees of Freedom

Many mechanical systems can change dimension. r θ l k/2 k/2 y v u v m φ Body 2 1 m v v θ Rake x l θ We are primarily concerned with the problem of determining controllability and the motion planning problem. Slide 1 This motivational slide is intended to illustrate two main points: • Changing dimensions is common, and • There is a natural kinematic/dynamic dichotomy in such problems, which will...
