摘要: 基于Matlab的建模仿真,采用PID调节,设计一种斯特林发动机功率控制方法,对GPU-3β型斯特林发动机以改变压力的方式进行功率调节。根据20组实际数值模拟出传递函数,模拟的数据与真实数据对比符合度高于99%。输入压力值通过传递函数计算得到实际的输出功率,调节输入压力值,输出结果随之改变。结果表明运用闭环负反馈和PID调节后,随着输入压力值的变化,输出功率能按特定的规律进行变化。本设计消除了输入数据的扰动以及外界干扰对输出功率稳定的影响,使得斯特林发动机的功率控制系统具有相对较强的稳定性以及对扰动具有一定的自适应能力。

Abstract: Based on simulation modeling in MATLAB, a Stirling engine power control method was designed with PID adjustment, which can control a GPU-3 Stirling engine by changing pressure. The transfer function was simulated based on twenty groups of real values. The agreement between the simulated data and the real data is higher than 99%. The input pressure value was calculated through the transfer function to obtain the actual output power. The simulation results show that with the closed-loop negative feedback and PID adjustment, the output power can vary according to the specific law with the change of the input pressure value. This design eliminates the influence of input data disturbance and the external disturbance on output power stability so that the power control method for the Stirling engine has relatively strong stability and certain adaptive ability to disturbance.

Key words: Stirling engines, simulation modeling, PID control, pressure, power control
