Integrated guidance and control with terminal impact angular constraint for bank to turn flight vehicle

An integrated guidance and control (IGC) method for bank to turn (BTT) flight vehicle with impact angle constraint is presented, using multiple sliding surface control theory. Based on missile-target engagement geometry model and BTT control mode, an IGC model is formulated. According to multiple sliding surfaces control theory, IGC laws are designed in pitch channel and roll-yaw channels respectively to satisfy miss distance and impact angle requirements. Numeric simulation results show that the aforementioned method can design IGC law for BTT missile effectively, the miss distance and impact angle constraints are satisfied properly.
