球杆系统常用于检验控制策略和控制理论的效果，如何整定优化球杆系统的控制参数具有重要意义。应用MATLAB软件进行仿真实验，对系统输入的控制参数P、D与系统输出的稳定时间、超调量之间的映射关系进行采样，并应用最小二乘算法进行拟合，进而建立基于数据驱动的球杆系统控制输入与输出的数学模型。经过验证表明建模精度较高，为控制参数优化设计提供了模型支持。
Ballbeam system is often used to verify the performance of control strategies and theories, which make optimizing the ballbeam system control parameters be of great significance. In this article, simulation experiments via the MATLAB software are firstly conducted. Subsequently, the P、D parameters are selected as input parameters while the settling time and overshoot amount are selected as output ones of the control system. Then, some sampled data reflecting the mapping relationship between the input and output of the control system are obtained. Further, the databased mathematical model which reflects the inputoutput of ballbeam control system is constructed by using the least square method. The final computational results demonstrate that the model accuracy is satisfactory, which will provide support for control parameters optimization.
