The controller is developed under a special nonlinear coordinate transform such that speed control objective can be fulfilled. The underlying design concept is to endow the closed-loop system while lacking the knowledge of some key system parameters, such as the rotor resistance, motor inertia, and motor damping coefficient. The proposed control scheme comes along with a thorough proof derived based on Lyapunov stability theory. Experimental results are also given to validate the effectiveness of the proposed control scheme. © 2006 IEEE.en-USAdaptive control; Backstepping analysis; Induction motors; Lyapunov stabilityAdaptive control systems; Lyapunov functions; Nonlinear control systems; Speed control; Backstepping analysis; Lyapunov stability; Induction motorsconference paper2-s2.0-39649088633http://ntur.lib.ntu.edu.tw/bitstream/246246/220781/-1/58.pdf
