[Abstract]:Aircraft power system (including main power supply, auxiliary power supply and emergency power supply etc.) is one of the most important systems of aircraft. It is responsible for flight control, navigation, radio communication, radar and electronic countermeasures. At the same time, the power supply quality of the aircraft power supply system is directly related to the normal operation of all kinds of electrical equipment on the aircraft, and then affects the flight safety and mission execution. Therefore, in the maintenance of aircraft power system performance testing and support put forward strict requirements. In order to ensure the detection requirements of aircraft power system and improve the reliability of aircraft power system, the aircraft power supply system is checked regularly with the help of special test support instruments to ensure that all the parameters of the test can reach the prescribed technical targets. In view of the complex test requirements of aircraft airborne power supply equipment and its accessories, a test platform for aeronautical power supply system is developed. This paper mainly studies the control technology of aeronautical power system test platform. In the test platform of aeronautical power supply system, a high-power high-speed drive motor is used to simulate the aircraft engine to drive the generator to work, and the performance parameters of the generator and its accessories are measured, so as to achieve the purpose of locating and checking out of position. In order to obtain good dynamic and static speed regulation performance of high power high speed drive motor, the simulation model of high power high speed drive motor is established in this paper, and three kinds of control strategies are simulated and analyzed. The test and control system is designed according to the running requirements of the upper computer, sub-test system and test resources of the test platform. In addition, the software system of the test platform is compiled under the LabVIEW2010 programming environment according to the platform test task. The full text mainly carries on the following several aspects of research work: 1. Studied the aeronautical power supply system related technical data, analyzed the system test task request, defined the test need. 2. This paper analyzes the functional requirements of the test platform for aeronautical power supply system, studies the overall idea of the platform design, and determines the research direction of three key problems of platform control technology. According to the speed regulation requirement of high power and high speed drive motor, the motor model is established, and the simulation analysis of three control strategies is carried out, and the direct torque control strategy .4is selected. The measurement and control system of the platform is designed, and the cooperative work of the host computer with each sub-test system and the test resources is completed. The programming of test resource control program and the construction of platform software system are completed in LabVIEW2010 programming environment.
