Coordinative operation design for multiple controllers with variable input parameters

This paper discusses the problems of coordinative operation between the steady state controllers and accelerating controller, and among the steady state controllers themselves. For the first problem, one control scheme of inner closed loop structure is proposed which modifies the input error of steady state controllers using measurement feedback. For the second one, considering the engineering simplification, a variable input parameter robust controller based on matching the channel gains is proposed, which changes the output choice into input error choice. Finally, the simulation is conducted for these two simplified schemes using controllers obtained from H, design controllers, which shows that the proposed methods can address the engineering application problem of multiple controllers coordinative operation arising from the aeroengine control systems.
