Abstract
To reduce the strong control coupling characteristics of a hypersonic vehicle, we perform the optimal design of minimal coupling among its channels by simplifying its control system design. We define the Degree of Control Coupling (DCC) and use it to evaluate the control coupling characteristics among the channels. We use the engineering estimation and the CFD calculation method to establish the DCC models and characterize the hypersonic vehicle configuration parameters, which are then optimized with the multi-objective particle swarm optimization algorithm to reduce the control coupling of its aerodynamic rudder. The simulation results, given in Fig.4, and their analysis show preliminarily that the hypersonic vehicle configuration control and optimization method can effectively reduce the control coupling characteristics of the hypersonic vehicle controlled by an aerodynamic rudder, which is also significant for its control system design.
