摘要

An aircraft engine is a multidimensional and highly parametric complex system with dynamics and strong non-linear behavior with stochastic properties. Many modern gas turbine engines today are centralized and specialized design by a highly integrated dual channel engine-mounted controller, such as a Full Authority Digital Electronic Controls (FADEC) to control all functions of the aircraft engines. In contrast to the centralized approach of the FADEC, the control architectures have been designed in which the functionality is more distributed around the engine to smart sensors, smart actuators and other subcomponents. The intent of these alternative architectures is to reduce overall system weight and improve reliability and diagnostics. Using fewer cables, the intent is also to reduce the functionality within the FADEC and to improve life cycle costs using improved fault diagnostics. Implementation of a distributed control of turbine engines constitutes practical realization of decentralized control architecture on a dedicated hardware. Such hardware realization of decentralized control architecture poses a new set of challenges. This paper provides an overview of solutions to some challenges associated with real world realization of decentralized control architecture on turbine engines in the form of a distributed hardware system. It also provides methodology used for the development and integration of a distributed control and diagnostics software for turbine engines. Developmental steps, implementation architecture and preliminary simulation results of the proposed distributed control system are reported in this paper. Preliminary results showed potential success of implementing distributed control of turbine engines.
