All-digital Design, Hardware And Software With The Dynamic Controller

Digital following-up controller is designed for improving the performance of modern weapons, according to the claim of modernization of the national defenses. Analog following-up system in use limits the further improvement of weapon precision, so it is quite meaningful to convert those analog systems to digital systems.Controller is the center unit of this following-up system. The performance of controller is the major factor affecting system function. As a result, how to design a better controller is important. My study focuses on the design of digital following-up controller.This dissertation describes the design of controller. It includes the design of circuit and programming. The main content is following:1. According to the principle of the double-pipe selsyn system, a conversion module is designed, it has a standard conversion interface (MultiBus-II), which makes it provide a digital position angle of high precision to core control module in time.2. Designing a core control module based on DSP. It not only provides the standard interface, which connects to conversion module, it also can protects control system and show many parameters of system.3. Developing optimum control stratagem by comparing many control stratagems based on the control characteristic of the following-up system. System realizes the self-adaptive control due to adopting forward-feedback and feed back multiple control stratagems.4. Programming based on Simulator (SEED-XDSPP) and code compiler (cc4. 10 version) and finishing the control algorithm.5. Digital controller can control objects in open-loop correctly.
