摘要
结合试验数据以仿真软件AMESim建立燃气轮机燃油执行机构高精度模型,由于流量系数、间隙泄露等非线性参数影响,高精度模型不能直接用于执行机构控制器的设计。本文以最小二乘法为手段,针对燃油计量活门位置控制系统进行辨识,得到该系统在稳态点的线性数学模型。
According to the experimental data, building the precise model of gas-turbine main fuel actuaor based on AMESim. Because of the affect the nonlinear parameters such as the flow coefficient, the gap leakage, etc, high precise model can not be used for actuator controller design directly. Combined with the least squares method, this paper carried identification of the main fuel metering valve position control system, obtained the linear mathematical model of the system in the steady state point.
