The Convergence Of Advanced Aircraft Electrical System Controller Design And Development,

Bus Controller (BC) is an important component in fulfilling the automation of aviation electrical load control and management, whose primary task is to monitor and control the major bus of aircraft's electrical system.According to the system requirements, the dissertation analyses the demands on BC in details, and establishes a whole scheme, which divides my research into four parts: ERT module, I/O module,bus communication module and power supply module. The sequent work is based on the design.The dissertation makes an audacious attempt at application of new technology and instruments. In view of numerous digital and analog signals need to be processed, and the difficulty of real-time processing of multi channel 400 Hz AC signal, VHDL ( VHSIC Hardware Description Language ) is applied to design the digital circuit, which is successfully realized in Field Programmable Gates Array IC-XC2S100. Therefore, the peripheral circuit is simplified, and the burden of CPU is relieved. The dissertation also makes detailed design for the other modules.Software development grounds on the embedded Real-Time Operation System. Top layer application is based on the RTOS, developed in hybrid programming of C and assembler language. Thus, the reliability and the real-time processing ability of the system are improved.
