Abstract:

According to the blended control problem of aerospace vehicle with multiple control effectors during the reentry phase, based on the characteristics of aerodynamic surfaces and pulsed reaction control jets, three different compound controller configurations are proposed:command configuration, moment configuration and command error configuration. The corresponding control laws are also developed to complete the control system design for the reentry phase of aerospace vehicle. Simulation results show that all of the three control systems have strong abilities of tracking command rapidly. The smoothest responding of aerodynamic surface and the least frequency firing of jets are achieved with the command configuration controller. According to the work of effectors, the command configuration controller is the most effective in practice.
