[Abstract]:The traditional design method of aero-engine electronic controller has the disadvantages of long product development cycle and high R & D cost, which can not meet the increasing demand for engine control. Rapid prototyping technology is based on the common hardware platform and code reuse automatic code generation technology to construct the controller prototype quickly, which can be used to test and verify the controller hardware and software scheme as soon as possible. Therefore, it can greatly improve the development efficiency and R & D level of the controller. Lab. VIEW is a convenient and fast graphical software programming environment, and its essence is code reuse. In this paper, the micro turbojet engine electronic controller is designed based on the idea of rapid prototyping, and the embedded code reuse technology based on Lab VIEW is studied. Firstly, the environment mechanism of Lab VIEW embedded software development is studied. Based on the integration of the new and old versions of the embedded software compilation environment Keil MDK called by Lab VIEW, the RTX embedded operating system for ARM Corte x M3 kernel in Lab VIEW is transplanted to the TM4C123 of the ARM Cortex M4 kernel used in this paper. The adaptive transformation of Lab VIEW development environment for micro turbojet engine controller software development has been completed. Secondly, the embedded software development process of Lab VIEW and the principle of code reuse are studied. This paper adaptively modifies the code reuse template for TM4C123 and develops the peripheral drive code by resource mode and script mode respectively. In addition, the handshake and working mode between Keil and Lab VIEW are studied more deeply, which solves the problems of how to initialize the interrupt and how to debug the embedded program in keil. Then, according to the control requirements of micro turbojet engine, a universal controller hardware circuit is designed, and the rapid prototyping of controller software is completed by using the Lab VIEW embedded software development environment. Finally, the hardware of the controller is verified by loop and bench tests. The test results show that the rapid prototype of the micro turbojet engine controller developed in this paper can meet the requirements of engine control. The graphical embedded software development of Lab VIEW is convenient and efficient. Can meet the increasing demand for engine control development.
