Digital Controller For A Common Development Platform Software Design And Implementation,

As an important part of aircraft power supply, Generator Control Unit can supervised the operating state of the power supply system by detecting the parameters such as voltage, electric current and frequency. It is used to regulate the output voltage, protect the system and equipments from fault, and communicate with NAMP. It has a function of built-in test in order to fault diagnosis.The algorithm of voltage regulator and database used for fault diagnosis is discussed based on X/XKVA variable frequency alternate power system. Firstly, the principle, structure and functions of GCU and hardware constitution are introduced. Then the theories of PID control, adaptive control and fuzzy control are introduced. Based on these theories, the algorithm is designed and simulated. The simulation results shows the algorithm has a high accuracy and strong robust. According to the characteristics, the faults database is designed. The database has a big volume of fault information and fault isolation is easily and efficiently. In order to insure the system reliability of software, the anti-interference methods are considered. At last, the algorithm of data acquisition and its implementation are described in detail.According to the requirements, the detail project is discussed and analyzed. The software architecture of universal develop platform is designed and implemented. This software platform can meet the requirements and has a good reliability and anti-interference capability. It provides a basic framework of software for the further implementation.
