基于MATLAB的数字PID控制器设计及仿真分析 摘 要 PID控制作为历史最为悠久，生命力最强的控制方式一直在生产过程自动化控制中发挥着巨大的作用。PID控制是最早发展起来的控制策略之一，由于其算法简单、鲁棒性好和可靠性高，被广泛用于过程控制和运动控制中。数字PID控制算法是将模拟PID离散化而得到的，各参数有着明显的物理意义，而且调整方便，所以PID控制器很受工程技术人员的喜爱。 本论文主要实现基于MATLAB的数字PID控制器设计及仿真。首先介绍了传统的模拟PID控制方法，包括比例控制方法、比例积分控制方法、比例积分微分控制方法等。接下来，介绍了数字PID控制。随着时代的发展，科技的进步，传统的模拟PID控制方法不能满足人们的需求，数字PID控制的改进算法也便随之而来。本文最后，应用MATLAB软件，在实验的环境下实现了其设计及仿真。 本次毕业设计用来完成数字PID控制器的设计，通过。与PID控制比较，该具有良好的性，而且。另外，esign and simulation analysis of Digital PID Controller MATLAB-based Abstract As the most age-old and powerful control mode, PID control always has had a great effect on the automatic control of the production process. PID control is one of the first developed control strategy, because of the simple algorithm， great robust and high reliability, it is widely used in process control and motor control. Digital PID control algorithm is gotten by discreting the analog PID control, and the parameters have obvious physical meaning and facility adjustment, so PID controller is popular with engineering and technical personnel. In the paper, the main idea is to accomplish MATLAB-based digital PID controller design and simulation analysis. In the first place, the traditional analog PID control methods is introduced, including proportional control methods, proportional integral control and proportional integral differential control. In the second place, the digital PID control methods are offered. With the development of the times, the advancement of technology, traditional analog PID control method cannot make a satisfaction, then digital PID control is followed. At last，the application of MATLAB software to achieve their design and simulation is easy to accomplish. The graduation project is to complete the digital PID controller design and simulation through MATLAB simulation and analysis. It is known that through the literature, compare with traditional PID controller, the controller has good flexibility and precision of the mathematical models available. I
