Abstract:In this paper, a sliding mode guidance law is designed for intercepting high speed and large maneuvering targets. A new error variable function is designed by combining the line of sight tracking error with the performance constraint function, so as to ensure that the line of sight angle of the guidance system can converge to the desired angle; the convergence speed of the line of sight angle is not less than the preset speed; and the maximum overshoot and convergence precision can satisfy the prescribed performance. The key concept in this approach is to transform the performance constraint problem into the bounded problem of the error variable function. In addition, the adaptive guidance law is designed to ensure the stability of the guidance system in the case of known upper bound and unknown upper bound. Simulation results show that the designed guidance law has good performance.
