基于主频预估的短波发射机功率自适应控制方法

Power Adaptive Control Method of Shortwave Transmitter Based on Main Frequency Prediction

现有控制方法存在机体坐标系不精确的问题,导致发射机收敛速度较慢,因此设计一种基于主频预估的短波发射机功率自适应控制方法。补偿发射机功率电抗,调整短波发射机功率不平衡结构,基于主频预估建立机体坐标系,确定其姿态角取值范围,构建动力学模型,读取末端电容值,定位短波发射机谐振点,利用遗传算法设置自适应控制模式,实现自适应控制方法设计。实验结果表明,此次设计的自适应控制方法比3种现有方法的收敛速度分别快16.7511 m/s、16.4446 m/s以及16.6617 m/s,证明融合了主频预估技术的方法应用效果更好。

The existing control methods have the problem of inaccurate body coordinate system,which leads to the slow convergence speed of the transmitter.The power reactance of the transmitter is compensated,the power imbalance structure of the shortwave transmitter is adjusted,the body coordinate system is established based on the main frequency prediction,the attitude angle range is determined,the dynamic model is constructed,the terminal capacitance value is read,the resonance point of the shortwave transmitter is located,and the adaptive control mode is set by using genetic algorithm to realize the design of the adaptive control method.The experimental results show that the convergence speed of this adaptive control method is 16.7511 m/s、16.4446 m/s、16.6617 m/s respectively,which proves that the application effect of the method combining the main frequency prediction technology is better.
