智能控制实验六：线性系统串联校正与频域曲线分析Matlab实现

"Experimental Report on Linear System Series Calibration in the Wit Automatic Control Principle Experiment This report documents the experiment conducted at Wuhan Engineering University on April 6, 2021, with the objective of familiarizing with MATLAB commands for plotting frequency domain curves, understanding the analysis and calibration methods within the frequency domain of control systems, and mastering the thought process and steps of series calibration design using frequency characteristic method. The experiment specifically aimed to achieve the following objectives: 1. Proficiency in plotting frequency domain curves using MATLAB commands. 2. Understanding the analysis and calibration methods within the frequency domain of control systems. 3. Mastery of the thought process and steps of series calibration design using the frequency characteristic method. The experiment involved the design of a lead correction device for a certain unit's negative feedback control system with an open-loop transfer function. The goal was to achieve a static speed error coefficient, phase margin, and gain margin after calibration. The original system's angular margin was calculated using the num0=20; den0=[1,1,0]; w=0.1:1000; [gm1,pm1,wcg1,wcp1]=margin(num0,den0;"...
