Nonlinear adaptive control of magnetic levitation system using terminal sliding mode and integral backstepping sliding mode controllers.

Magnetic levitation (MagLev) system is an unstable, highly non-linear and dynamically fast. These characteristics make it challenging task to design a suitable controller to ensure any object to stay at a certain distance from the electromagnet with negligible error. It can be achieved by generating the required flux with the help of a control input.

Non-linear control for electric power stage of fuel cell vehicles.

Tough driving conditions like hilly areas, slippery roads, rough terrains and high-speed driving dominate the effects of non-linearities present within each component of a vehicle. Such conditions cause the behavior of components like energy sources, power processing blocks and electric traction motors to deviate from their nominal behavior. This research work presents two non-linear control methodologies, one being Lyapunov and Backstepping based controller loops and the other being Synergetic based controller loops for these vehicles.
