Abstract
Aero-engine is the power source of Unmanned Air Vehicle (UAV), its dynamic
and static characteristics directly affect the performances of UAV. Engine control is
the foundation of UAV flight control system, and the key factor to realize autonomous
flight. An excellent Engine Control System (ECS) doesn’t exist without the supports
of corresponding hardware and control algorithm. This paper focuses on the design
and implementation of software and hardware and the design of ECS control law.
Firstly, the constituent parts, the architecture and the functions of ECS were
designed according to the requirements of engine control. Secondly, the requirement
analyses about hardware were made, the devices such as flight puter,
sensors, data-link units and ground control station were selected, and then the
hardware architecture of ECS was achieved. Through analyses parisons of
different software development environments, the appropriate one was chosen. By
using it, the airborne programs of engine controller with real-time performance and
reliability were developed; the control and monitoring software running on ground
station with perfect functions, easy operations and convenient transplantation were
then developed. Thirdly, the adaptive PID control concepts were introduced to design
an engine controller
