Inverted pendulum system is a typical rapid, multivariable, nonlinear, absolute instability and non-minimum phase system, and it is a favorite problem in the field of control theory and application. In its control, the current main control method includes in fuzzy control, variable structure control and robust control etc. For fuzzy control of a double inverted pendulum, the research is focused on...
With the characteristics of non-linearity, large time delay, and strong disturbance, the web tension control is the main difficulty of the re-winder electrical control system. The conventional PID algorithm can not achieve good performance index when the re-winder is working under acceleration or deceleration. The new algorithm based on fuzzy control adaptive PID algorithm could solve this problem,...
We develop a PID based fuzzy logic pitch attitude hold system for a typical fighter jet under a variety of performance conditions that include approach, subsonic cruise and supersonic cruise. In this approach, the gains found in a classic PID controller are replaced with fuzzy systems, still contributing the overall effects of a proportional, integral, and derivative controller. The response is compared...
