An adaptive fuzzy robust controller is designed to improve the electrode control of three-phase electric arc furnace electrode regulator system. The design process of robust fuzzy control system is proposed in detail. The impacts of tracking error and approximation error to parameter adaptive law are considered. The approximate error and external disturbances compensate controls are adopted. The simulation...
This paper analyses the characteristics of the arc furnace electrode regulator system, and also a design of fuzzy-PID control system. In order to to improve the performances of the fuzzy controller, the genetic algorithm is introduced to optimize parameter of fuzzy-PID controller. The simulations show that satisfied control effects can be achieved using optimal parameter of fuzzy-PID based on genetic...
The design of robust Hinfin controller for a class of uncertain neutral systems with varying state delay and input control delay is considered. The uncertainties are norm-bounded and the states of the uncertain neutral systems are available. Combining the linear matrix inequality with Lyapunov functions by proper assumption, the existent conditions of quadratic stabilization and Hinfin state feedback...
