“自动控制原理”实验教学改革创新与实践

Reform and Innovation and Practice of "Automatic Control Theory" Experimental Teaching

随着本科毕业生数量的增多,没有实践经验和创新意识的毕业生将会在就业的大军中处于不利地位。而实验教学是培养学生独立思考和创新能力的重要途径,因此对于自动化专业的核心课程"自动控制原理",更应该进行实验教学的改革。以其中一个实验"线性系统的时域分析"为例,提出一种发挥学生主动性的自己动手设计实验电路图、实际电路连接、仿真验证的方案,通过虚拟示波器上的二阶系统过渡过程的阶跃响应曲线和Matlab仿真结果的对比,更好的理解二阶系统在不同参数条件下的状态。既增强了对知识点的理解,又培养了学生的独立思考及动手能力,充分调动了学生的学习积极性,将传统意义上学生被动学习的角色转变。

With the increase in the number of graduates,those who don't have the experiment of practice and the sense of innovation will not stand at a better chance in finding a good job.Since experimental teaching is an important way to cultivate the students the independent thinking and the capacity of innovation,as far as 'automatic control theory' is concerned,which is the core curriculum of the major of automation,experimental teaching should be reformed.To take one of the experiments which are called 'linear system of time-domain analysis' for an example,it proposes a solution in which the students can design the circuit diagram all by themselves and connect the actual circuit and finally verify the simulation.Though the comparison of the Matlab simulation result and the step response curve,which is resulted by the second-order transition on the virtual oscilloscope,we can have a better understanding of the status of the second-order system with different parameters.Thus not only enhancing the understanding of the principal knowledge,but also cultivating the capacity of the independent thinking and hands-on ability,which fully mobilize the enthusiasm of students,and accomplish the role changes of the traditionally passive-learning of students.
