IEEE TRANSACTIONS ON AUTOMATIC CONTROL, VOL. 43, NO. 3, MARCH 1998 391 III. CONCLUSION A New Approach to Dynamic Feedback Linearization We have presented a new type of approximate solution for non- Control of an Induction Motor linear optimal control problems by making use of the concept of John Chiasson pseudolinearization. This approximation is expected to be less local than the standard linear-quadratic approximation about a single equi- librium, as is indicated by the relationship between the corresponding Abstract— A new approach to dynamic feedback linearization control control laws as well as a comparison of the corresponding closed- of an induction motor is given. Previously, it has been shown that the loop stability properties. Certainly this expectation is illustrated by dynamic model of an induction motor, consisting of speed, stator currents, our examples. Also, the available computational tools for Riccati and rotor fluxes, is dynamically feedback linearizable [1]. However, the equations and the method for computing (x) via splines in [1] controller and transformation were valid only as long as the motor torque was nonzero and the methodology required switching between indicate that in computational difficulty our approach is somewhere two computationally complex transformations. Here it is shown tha
