直流电动机双闭环调速系统的动态特性研究与仿真毕业论文 Simulation Research on Speed Regulation System of Double Closed Loop of DC Motor ABSTRACT DC motor has a good effect, braking performance, appropriate for smooth speed control in a wide range, and DC speed control system both in theory and practice more mature, is to study the basis of other control system. The DC converter using MATLAB software system for simulation of virtual environments is not only easy to use, but also greatly reduce the research costs. This paper describes the basic principle of DC motor and speed control principle, introduced the open-loop DC motor and dual-loop speed control system components and the static and dynamic characteristics, and according to the basic equation of DC motor speed control system construction established a mathematical model diagram shows the dynamic structure, designed by engineering design of DC SpeedRegulation system. Finally, the simulation software MATLAB simulation model built on the speed control system was simulated. By DC Motor SpeedRegulation of the dynamic characteristics and simulation, we can see clearly, double-loop DC motor speed control system has good dynamic performance, you can within a given speed, a smooth static error-free speed, which for the DC motor speed control system hardware to provide a theoretical basis for experimental Key words: Speed control of DC-drivers;Double-closed-loop;Current regulator;Speed regulator;Computer simulation 毕业设计(论文)原创性声明和使用授权说明 原创性声明 本人郑重承诺:所呈交的毕业设计(论文),是我个人在指导教师的指导下进行的研究工作及取得的成果。尽我所知,除文中特别加以标注和致谢的地方外,不包含其他人或组织已经发表或公布过的研究成果,也不包含我为获得 及其它教育机构的学位或学历而使用过的材料。对本研究提供过帮助和做出过贡献的个人或集体,均已在文中作了明确的说明并表示了谢意。 作 者 签 名: 日 期: 指导教师签名: 日 期: 使用授权说明 本人完全了解 大学关于收集、保存、使用毕业设计(论文)的规定,即:按照学校要求提交毕业设计(论文)的印刷本和电子版本;学校有权保存毕业设计(论文)的印刷本和电子版,并提供目录检索与阅览服务;学校可以采用影印、缩印、数字化或其它复制手段保存论文;在不以赢利为目的前提下,学校可以公布论文的部分或全部内容。 作者签名: 日 期: 学位论文原创性声明 本人郑重声明:所呈交的论文是本人在导师的指导下独立进行研究所取得的研究成果。除了文中特别加以标注引用
