PAGE PAGE I 摘 要 本论文以温度控制系统为研究对象设计一个PID控制器。PID控制是迄今为止最通用的控制方法，大多数反馈回路用该方法或其较小的变形来控制。PID控制器（亦称调节器）及其改进型因此成为工业过程控制中最常见的控制器 (至今在全世界过程控制中用的84%仍是纯PID调节器，若改进型包含在内则超过90%)。在PID控制器的设计中，参数整定是最为重要的,随着计算机技术的迅速发展，对PID参数的整定大多借助于一些先进的软件，例如目前得到广泛应用的MATLAB仿真系统。本设计就是借助此软件主要运用Relay-feedback法，线上综合法和系统辨识法来研究PID控制器的设计方法，设计一个温控系统的PID控制器，并通过MATLAB中的虚拟示波器观察系统完善后在阶跃信号下的输出波形。 关键词： PID参数整定 ；PID控制器 ；MATLAB仿真；冷却机； Design of PID Controller based on MATLAB Abstract This paper regards temperature control system as the research object to design a pid controller. Pid control is the most common control method up until now; the great majority feedback loop is controlled by this method or its small deformation. Pid controller (claim regulator also) and its second generation so become the most common controllers in the industry process control (so far, about 84% of the controller being used is the pure pid controller, it’ll exceed 90% if the second generation included). Pid parameter setting is most important in pid controller designing, and with the rapid development of the computer technology, it mostly recurs to some advanced software, for example, mat lab simulation software widely used now. this design is to apply that soft mainly use Relay feedback law and synthetic method on the line to study pid controller design method, design a pid controller of temperature control system and observe the output waveform while input step signal through virtual oscilloscope after system completed.
