Robust Control of an Induction Motor Drive with Lyapunov Filter and Linear Quadratic Regulator

-This paper addresses a two degree of freedom structure discussed by Kreisselmeier for the SISO case in 1999. The discussion herein considers a MIMO setting, and aims at the use of this control topology for robust and fault tolerant control. It is also shown how design barriers can be obtained for robust I/O transfer behavior assignment and robustness evaluation schemes can be devised which allow for the quantitative valuation of I/O transfer behavior degradation in the presence of plant model uncertainty. The concepts and techniques are illustrated and assessed using an in-flight simulation problem.

The current source inverter(CS1)-fed induction motor (IM) drive system is an open loop stable system, however due to model uncertainties and operation at different operating points the system exhibits poor performance and may loose stability. This paper utilizes the H , Loop Shaping Design Procedure (LSDP) with p -analysis ( p LSDP) to design a controller for a CSI-fed induction motor drive system in order to achieve robust stability and robust performance against various model uncertainties.First, the nonlinear dynamic equations of the CSI-fed IM are described in state space form, with emphasis on modeling errors (uncertainties), physical disturbances and noises, then these equations are linearized around an operating point. Second, the H , LSDP with p -analysis procedure is explained. Third, the H , LSDP problem formulation is presented with emphasis on the selection of the frequency shaping functions which reflects the robust stability and performance goals. Finally, the p LSDP is applied to the controller design of an example system, and numerous simulation results are presented. The results showed that both robust stability and robust performance are achieved.
