Control Systems
控制系统是电气工程与自动化专业的核心课程，讲授反馈控制系统的建模、分析与设计方法。课程内容包括线性系统数学模型、传递函数与方块图、状态空间描述、时域性能指标与稳定性判据、根轨迹法、频域分析中的伯德图与奈奎斯特判据、PID 控制器设计与超前滞后校正。结合 MATLAB/Simulink 仿真，培养学生对实际工程系统的分析设计与调试能力。
Control Systems is a core course for electrical engineering and automation majors, teaching modeling, analysis, and design of feedback control systems. Topics include mathematical models of linear systems, transfer functions and block diagrams, state-space representation, time-domain performance and stability criteria, root locus, Bode plots and Nyquist criterion in frequency-domain analysis, and PID controller design with lead-lag compensation. Combined with MATLAB/Simulink, it develops practical analysis, design, and tuning skills.
学生建立直流他励电机的数学模型，在 Simulink 中搭建闭环调速系统，分别采用试凑法与 Ziegler-Nichols 法整定 PID 参数，对比单位阶跃响应的上升时间、超调量与稳态误差。要求设计串联校正装置使系统满足给定性能指标，撰写报告并提交仿真模型与参数整定过程文档。
Students model a separately excited DC motor, build a closed-loop speed control system in Simulink, tune PID parameters using trial-and-error and Ziegler-Nichols methods, and compare rise time, overshoot, and steady-state error of the unit step response. They design a series compensator to meet given performance specifications, and submit a report with simulation model and tuning documentation.
