This technical brief emphasizes on the control of polymer electrolyte membrane fuel cell (PEMFC) air supply system. The objective is to improve net power output through adjusting oxygen excess ratio within a reasonable range. In view problem that PEMFC system difficult achieve accurate modeling and stable control, robust adaptive controller proposed by utilizing exact linearization radical basis function (RBF) neural network (RBFNN) does not need complete structure parameters unmodeled...
Control aims to avoid oxygen starvation and maximize the net power output by maintaining optimal excess ratio (OER), which varies between 1.8 2.5. Because of nonlinearity proton exchange membrane fuel cell (PEMFC) air supply system different conditions, ensuring an OER is still a challenge. In this study, model-free adaptive controller presented for PEMFC based on feedback linearization interval type-2 fuzzy logic systems (IT2 FLSs). Theoretical analysis experimental results verify...

The event-triggered tracking control is studied for the steer-by-wire (SbW) system with actuator fault, inaccurate dynamic model, and external disturbance. First, an adaptive sliding mode based on event-triggering mechanism proposed. lumped nonlinearity, including friction torque self-aligning of SbW systems, approximated by robust radial basis function neural network (RBFNN). Robust terms attenuate negative effects modeling error, disturbance, error performance. More importantly,...
In this paper, an observer-based adaptive neural network controller is developed for the Steer-by-Wire (SbW) system of automated vehicles with uncertain nonlinearity and unmeasured state. An observer introduced to estimate angular velocity front wheels, so hardware cost complexity mechanical structure electronic circuits are reduced. Then, proposed SbW achieve excellent steering precision. A radial basis function (RBF) used model nonlinearity, which mainly includes self-aligning torque...
Storage of 10 Tb/in2 in hard disk drives requires a physical spacing the level 0.25 nm at read-write transducer location. A lot and tribology issues exist to such low flying height. At small intermittent contact solid-to-solid solid-to-liquid between slider surface becomes inevitable, which motivates improvement needs for present MEMS-based thermal fly-height control (TFC) technology satisfy future storage needs. How reduce touchdown instability eventually eliminate bouncing has been...
