This paper proposes the analysis and design of robust fuzzy control to nonlinear systems with time delay. The nonlinear system to be controlled, is studied in the context of Linear Parameters Varying (LPV) systems, it is partitioned into several linear sub-models of second order with time delay, in terms of transfer function, forming a convex polytope. Once defined the linear sub-models of the plant,...
PID control is widely used to control stable processes, however its application to unstable processes is less common. In the paper, the formulas are derived to tune PID controller for unstable processes with time delay to meet sensitivity specification. It adopts two feedback loop design technique, and obtains a tuning method for PID controller with setpoint weighting which can overcome structural...
A novel planar magnetic suspension stage has been presented in this paper, a decoupling control approach based on dynamic inversion has used for planar magnetic suspension stage system that is a nonlinear, multivariable and strong coupling system. So this method makes the complicated system becomes simplify and linear. The disturbance has been suppressed by using the disturbance observer. The result...
In the continuous casting process, various control strategies are used to reduce the mold level fluctuations which cause surface defects in the final product. This paper proposes a control structure able to improve the reduction of the bulging effect on the mold level. It is based on the Astroumlm's modified Smith predictor scheme which presents the advantage that the setpoint response is decoupled...
In this paper, we present a polynomial solution to a particular Hfrinfin control problem, which arises in the robust stabilization of a SISO plant when the uncertainty is described by the gap metric, nu-gap metric, pointwise gap metric, or normalized corprime factor perturbation. Compared with the existing state space solution, the polynomial solution appears simpler and more elementary. It boils...
