A novel adaptive fuzzy control method is proposed in this paper for a class of nonlinear disturbed systems which are subject to both lock-in-place and loss of effectiveness actuator faults. Nonlinearly parameterized fuzzy systems are employed to approximate the unknown functions in the control design, and additional control is included to deal with the approximation error as well as the external disturbance...
Adaptive fuzzy control is used to control a class of unknown nonlinear systems with perturbed dead-zone input in this paper. A new dead-zone actuator model which contains time-varying and perturbed actuation gain is proposed. The dead-zone nonlinearity is treated as a linear term, a nonlinear term and a disturbance-like term. Nonlinearly parameterized fuzzy logic systems are used to approximate the...
Because of the considerable change of surrounding temperature caused by the relatively long time in heating, it is rather difficult to stabilize the furnace temperature, when verifying thermocouples in auto-verification furnace at high temperature, in that case changes of the parameters of the furnace temperature mode occur, which results in worsened effects on the controller. In order to adapt the...
