Abstract :
PNG law which is one of the most widely used in missile guidance needs tuning of a constant parameter of the law. Under time delayed look angle measurement, we have to select the parameter carefully since the control loop may diverge. In this paper, based on the stability analysis for time delayed system, we proposed the range of the constant parameter which guarantees the stability even when time delay of the look angle measurement exists. Through simulation results, we verified our theoretical result.
