Robust Stabilization Control Based on Guardian Maps Theory for a Longitudinal Model of Hypersonic Vehicle

الملخص EN

A typical model of hypersonic vehicle has the complicated dynamics such as the unstable states, the nonminimum phases, and the strong coupling input-output relations.

As a result, designing a robust stabilization controller is essential to implement the anticipated tasks.

This paper presents a robust stabilization controller based on the guardian maps theory for hypersonic vehicle.

First, the guardian maps theories are provided to explain the constraint relations between the open subsets of complex plane and the eigenvalues of the state matrix of closed-loop control system.

Then, a general control structure in relation to the guardian maps theories is proposed to achieve the respected design demands.

Furthermore, the robust stabilization control law depending on the given general control structure is designed for the longitudinal model of hypersonic vehicle.

Finally, a simulation example is provided to verify the effectiveness of the proposed methods.
