Digital Servo System Design Based On PCI Bus

With the development of control technology, servo system is widely used in military industry and civil industry. This paper focuses on the type of SKJ-PCI digital servo system. To reinforce the content of the experiment and improve its effect, developing new software according to the hardware is needed. Besides of the primary content, algorithm design self-design and experiments are added to the new software.Under the environment of Windows XP, Visual C++6.0 is used to complete the procedure and algorithm design with a computer as the main control device. This procedure establishes the communication between SKJ-PCI data acquisition controlling plane and computer. The program includes zero adjustment, parameters setting, PID control as well as algorithm design self-design and tests. The paper puts stress on the mind and flow of design. Through calling MATLAB engine, it has finished drawing curves of response.Taking advantage of the program, it could help to do experiments of digital servo system.
