Adaptive Fuzzy Sliding Mode Control for Uncertain Nonlinear Systems Against Actuator Faults
In this paper, we propose to combine the fuzzy sliding mode control to tolerate actuator faults of unknown nonlinear systems subject to external disturbances. In particular, the idea of using adaptive fuzzy system to tolerate actuator faults of unknown nonlinear systems by approximating the system functions and the effects caused by actuator faults are avoided by the control structure. On the b...
متن کاملAdaptive Backstepping Control of Systems with Uncertain Nonsmooth Actuator Nonlinearity
In this paper, we present a new scheme to design adaptive controllers for uncertain systems containing nonsmooth nonlinearities in the actuator device. The control design is achieved by introducing certain well defined sign functions and Neural Networks approximations and by using the backstepping technique. For the design and implementation of the controller, no knowledge is assumed on the unk...
متن کاملAdaptive Backstepping Fuzzy Control Based on Type-2 Fuzzy System
A novel indirect adaptive backstepping control approach based on type-2 fuzzy system is developed for a class of nonlinear systems. This approach adopts type-2 fuzzy system instead of type-1 fuzzy system to approximate the unknown functions. With type-reduction, the type-2 fuzzy system is replaced by the average of two type-1 fuzzy systems. Ultimately, the adaptive laws, by means of backsteppin...
متن کاملControl Reconfiguration of a Boiler-Turbine Unit After Actuator Faults
Boiler-turbines are one of the most important parts in power generation plants. The safety problem in such systems has always been a special concern. This paper discusses the application of control reconfig uration by fault-hiding approach for a boiler-turbine unit. In Fault-hiding approach, after occurrence of a fault, nominal controller of the system remains unchanged; instead, a reconfigurat...
متن کاملADAPTIVE BACKSTEPPING CONTROL OF UNCERTAIN FRACTIONAL ORDER SYSTEMS BY FUZZY APPROXIMATION APPROACH
In this paper, a novel problem of observer-based adaptive fuzzy fractional control for fractional order dynamic systems with commensurate orders is investigated; the control scheme is constructed by using the backstepping and adaptive technique. Dynamic surface control method is used to avoid the problem of “explosion of complexity” which is caused by backstepping design process. Fuzzy logic sy...
