Problems solved by technology

The limitation of this type of method is that the selection of steady-state operating points is usually based on experience, and its number is limited. A series of engine linear models obtained in this way cannot perfectly describe the overall performance of the engine, especially at each steady-state operating point. In addition, there is no precise correspondence between the controller and the controlled system in this area, and its control performance needs to be improved.

Abstract

The invention discloses an aeroengine steady-state loop proportional integral controller and a design method and device thereof. The method comprises steps that an aeroengine T-S fuzzy model is established for an aeroengine steady-state loop, the aeroengine T-S fuzzy model is composed of at least one fuzzy sub model, and each fuzzy submodel is a linear system model near a steady-state linear operating point of an aeroengine; a steady-state loop proportional-integral controller is designed for the aeroengine based on the aeroengine T-S fuzzy model. The method is advantaged in that through combining the T-S fuzzy model with PI control, the method is more practical than combining with state feedback control and is more suitable for the aeroengine engineering, based on the T-S fuzzy theory, the aeroengine T-S fuzzy model is established, the steady-state loop PI controller is designed based on the model, and steady state performance control of the full speed range of an engine rotor can berealized through the fuzzy PI controller designed.

Description

technical field [0001] The invention relates to the field of aero-engine control, in particular to an aero-engine steady-state loop proportional-integral controller and a design method and device thereof. Background technique [0002] Aeroengine is a highly complex nonlinear system, which has a wide operating range under the influence of external conditions and the characteristics of internal components. In order to make the various components of the engine operate stably and reliably under any environmental conditions and any working conditions, it must be reasonably controlled to fully exert its performance benefits. [0003] The control of the working phase of the aero-engine is mainly divided into steady-state loop control and acceleration and deceleration control. In the state of acceleration and deceleration, the performance of the system is in a dynamic process, so the requirements for its controller performance cannot be verified very accurately. However, for the c...
