摘要
This paper proposes a new proportional-Integral (PI) guidance law for maneuvering targets interception. We first investigate the physical interpretation of the PI guidance law and the analysis results reveal that the PI guidance law is exactly the same as a direct model reference adaptive guidance law: the integral term in PI control plays the same role as the adaptive law in adaptive control. Based on this fact, we suggest a new PI guidance law by leveraging a modified reference model to improve the transient performance. Numerical simulation results are conducted to validate the analytic findings.
