IMPLEMENTATION AND TESTING OF SAMPLED-DATA H∞ CONTROL OF JET ENGINES

摘要

This paper shows how H∞-design methods successfully can be used for control of jet engines in a multivariable framework. The work concludes experiences from both analysis and design studies concerning control of the Volvo Aero jet engine RM12, which is currently placed in the Swedish air fighter JAS39 Gripen. The emphasis is on useful methods for design and implementation of H∞- controllers. The work considers selection of operating points and choice of weight functions for dierent specific tasks, design of sampled-data H∞-controllers of low order, and finally analysis of the closed loop system.
