摘要
扭转振动装置是一个高性能的实验平台,既可以模拟许多实际物理对象中存在的扭转振动的物理现象,同时通过不同的配置结构,又能够等价为不同阶次和自由度的控制对象。为了丰富本科生的创新实验课的内容,使学生掌握现代控制理论的控制方法,以扭转振动装置作为硬件平台开展了控制方法的实验研究。介绍了装置的组成,推导了其机械部分的等价数学模型。将该数学模型作为被控对象,提出了使用线性二次型调节器进行控制器设计的方法,通过计算得到相应的控制器参数,并且利用装置的应用软件进行了仿真验证。实验结果表明,所设计的控制器具有良好的控制性能。
Torsion vibration device is a high performance experimental platform which can not only simulate the phenomenon of torsion vibration in many practical objects,but also be equivalent to some control objects that are with different orders and freedom degrees. In order to enrich the content of innovational experiment and make students to master the design method of the modern control theory,the experimental research on the control method is carried out using the torsion vibration device as a hardware platform. Firstly,the structure of system is introduced and the equivalent mathematical model of the mechanical part is derived. Based on mathematical model,the method of linear quadratic regulator is proposed for designing controller. The parameters of controller are obtained by calculation. The simulation is conducted by applying software of device. The resulting simulation curves demonstrate that the designed controller has good control performance.
