Abstract
In automatic flight control system or autopilots, multiple specifications criteria are needed to be satisfied concurrently, such as good holding (small static altitude holding error), fast response, smooth transition (less oscillation, overshoot). So how to design the MSS (Multiple Simultaneous Specification) controller effectively and practically is a very significant and challenging job. Liu proposed a MSS controller design method (Liu and Mills, 2000). In this paper, we further apply the method together with the fine-tuning technique to the 6DoF nonlinear F-16 fighter longitudinal control channel. Simulation results show its applicability to nonlinear flight control system.
