Development of Motor Control for Hybrid Vehicle using Gain-scheduled H-infinity Control 2007-01-0269

Single tooth winding Interior Permanent Magnet (IPM) motors are widely used for Hybrid Electric Vehicles (HEV) and Fuel Cell Electric Vehicles (FCEV). Because of its structure, however, the higher spatial harmonic may appear and induces strong nonlinear characteristics. The control system therefore requires high response and robustness control.

In this paper, we introduce a systematic method to design a gain-scheduled H∞ controller with high level of robustness for IPM motor control system.

It is generally adopted that the designer makes model data first before designing a controller. On the other hand, this paper presents the method to treat uncertain parametric model and controller synthesis simultaneously. Experimental result is demonstrated and shows that our method achieves superior performance to the existing methods.
