本文分析了可调桨(CPP)控制系统的动特性。研究了系统——非线性和线性——的数学模型,对它进行了数字的和模拟的分析计算,得到了它们的稳态解和动态响应,给出了螺距控制精度和系统稳定性数据以及阀的特征系数,用数字计算和模拟的方法求解了实际系统的不稳定区。研究结果表明,不稳定是可以避免的,还指出了提高精度的途径。根据线性化的数学模型给出了一个简化的模拟关系,以供进一步的应用。
This paper analyzes the dynamic characteristics of the adjustable propeller (CPP) control system. The mathematical model of the system - nonlinear and linear - is studied. The numerical simulation and the numerical simulation are carried out. The steady-state solution and dynamic response of the system are obtained. The control precision of the pitch and the stability of the system are given. The characteristic coefficient of the valve, the numerical calculation and the simulation method solves the instability area of the actual system. The results show that instability can be avoided, and ways to improve accuracy are also pointed out. According to the linearized mathematical model, a simplified simulation relationship is given for further application.
