High Speed And High Precision Anti-aircraft Artillery Digital Servo System Is Developed

The performance of contemporary weapon systems has been enhanced by the development of military high-tech and the extensive usage of digital technology. The research of alternating current digital servo system with permanent magnetic electromotor and KOLLMORGEN drives based on industrial computer and windows operating system was required by the Weapon Department of the Navy.We have finished these tasks during the research: 1.We have designed a digital servo system agreeting to the Navy' s requires, selected the parts and set up their parameters fully. In order to access the servo system' s hardware we have developed a ISA (Industrial Standard Architecture) card by ourself.2. We have analyzed the architecture of modern digital servo system and proposed a complex control method. The principle of it was analyzed and simulated with Matlab6. 1.3. A VxD(Virtual Device) of the ISA card is designed and a real-time servo control system under windows 9x operating system is realized with the virtual interrupt technique.4. In order to measure the performance of the servo system extensively we have developed an intelligent loading system and have tested the servo system with different typical loads.The servo system runs well in the experiments with a friendly user interface and can be operated conveniently. The ends of the tests mean that the digital servo system has fulfilled the targets proposed by the Navy.
