3 ) definition of input designer concept for flight control system ( fcs ) . a input designer was successfully constructed which can provide a effect almost the same as directly control over aerodynamic control surface through the careful design of inputs of fcs . this input design concept is very important for in - service aircraft upgrade where change of the original pcs is not allowed 3 )提出了飞控系统输入设计概念，并成功地构建了飞控输入设计器，能够在不改变原飞控系统条件下有效地提高舵面控制能力，获得接近直接舵面操纵的性能，对于现役飞机改进、改型中飞机运动自动控制系统的设计具有非常重要的意义。
