采用系统模拟辨识的方法,把一个十三阶的飞行器自动驾驶仪数学模型降为七阶,验证结果表明,该七阶模型能够较好地反映原有系统的特性,具有工程实际应用价值。 By using the method of system simulation identification, a 13-order aircraft autopilot math model is reduced to seven order. The verification results show that the seven-order model can better reflect the characteristics of the original system and has practical application value.
