Design and simulation of KKV control scheme

Three kinds of thrust model for mini-engine to control trajectory and attitude of KKV (Kinetic Kill Vehicle) were designed and constructed. In the full paper, we explain our design and simulation in some detail. In this abstract, we just add some pertinent remarks to listing the three topics of explanation. The first topic is: the model of the mini-engine for controlling trajectory and attitude. In the first topic, we discuss how, based on changing control requirements, to switch from time to time to the suitable one of three modes-continuous pulse, intermittent pulse, and single pulse-of the mini-engine to achieve the desired control of trajectory and attitude. The second topic is: the design of control law. In the second topic, we, aiming at reducing the frequency of switching on and off and improving homing precision, explain how to calculate the threshold values for controlling 'on' and 'off'. The third topic is: the simulation of the terminal guidance trajectory of KKV. The simulation results, presented in two tables in the full paper, show preliminarily that the KKV can hit the target using the overload provided by mini-engine in the case of small mobility of the target.
