Abstract In order to realize reusable winged sub-orbital transportation system, the Space Systems Laboratory, Kyushu Institute of Technology has worked in research, development, and flight test for winged rocket which is called “WIRES” (WInged REusable Sounding rocket) since 2005. Autonomous flight system is one of the most important research fields for space transportation system. As space transportation vehicles have important nonlinear dynamics, control system design tends to be complex and difficult. Dynamic inversion (DI) is known as one of effective nonlinear control theories, and authors try to apply DI theory to attitude control for WIRES. DI controller is concerned about increment computational costs, because it is necessary to calculate the inverse dynamics. In this research, authors evaluate the calculation cost of DI controller by implementing to WIRES#015 which is subscale test vehicle of suborbital flight. As a result, the cost is small enough compared to control cycle. It can be said that the microcomputer has enough performance to realize longitudinal attitude control.
