Comparison Between Controllers of Polynomial Fuzzy Control System

In order to improve the control performance, a so-called lumped disturbanceis considered in the polynomial fuzzy model. As a result, two fuzzy controllers are proposed, in which one involves a disturbance observer. Though both controllers are able to stabilize the control system, computer simulations conclude that the performance by the one with the disturbance is better than the other when it comes to the lumped disturbance in the system concerned.
