This paper presents a speed controller for an interior permanent magnet synchronous motor (IPMSM) based on adaptive backstepping method. IPMSM speed is acquired through extended-EMF method, which is simple to achieve and has a good dynamic performance. A novel nonlinear control strategy, backstepping, is used to design speed tracking and current controllers. The system can achieve fast speed tracking...
This paper describes a practical implementation of simple control algorithms on a 6DoF quadrotor flying in an uncontrolled environment and being equipped with inexpensive sensors. A significant number of control algorithms that apply dynamic inversion or backstepping techniques on simplified state variable models of the vehicle dynamics are present in the literature, but they are only tested in simulations...
