Active Generalized Predictive Control of Aero-engine Turbine

摘要：

The active control of turbine blade tip clearance continues to be a concern in the design and control of gas turbines. Ever increasing demands for improved efficiency and higher operating temperatures require more stringent tolerances on turbine tip clearance. The nonlinear dynamical models of turbine tip clearance and certain aircraft and aero-engine, a turbine tip clearance apparatus, and an implicit active generalized predictive control are presented in this paper. The active clearance control of aeroengine turbine tip is evaluated in a lapse-rate takeoff transient. The results show the resultant active tip clearance control system has good steady and dynamic performance and benefits of increased efficiency, reduced specific fuel consumption, and additional service life.
