Nowadays, interceptor missiles have to overcome a variety of ever-evolving threats that significantly magnify the requirements of the interceptor design. This research focused solely on the autopilot and guidance system, where perfect information on the states is assumed, so that an estimator is not required in the loop. There are two main approaches to design autopilot and guidance systems: “Single-Loop” and “Two-Loop”. In the ” Two-Loop ” case, the inner autopilot loop is designed independently of the outer guidance one, whereas in the ” Single-Loop” case, the guidance command is injected directly to the actuator, without a definite autopilot. The main goal of the research was to identify the merits of each approach, and combine the benefits of the two approaches into a new improved one that has the potential to improve the missile’s performance and meet advanced design requirements.
In the talk, the merits of each design approach will be discussed. The conditions for obtaining equivalence between the “Single-Loop” and “Two-Loop” design approaches will be established under linear quadratic optimal control and differential game formulations, and for nonlinear systems with bounded controls. Broadly speaking, an equivalence relation between these two design approaches holds if full-state feedback exists and the number of guidance commands is equal to the number of available controls. The performance of the “Single-Loop” and “Two-Loop” approaches is demonstrated via simulations.
The talk will be given in Hebrew
