To reduce the impact on the flight safety from the translation and extraction of inner cargo in a flying aircraft, we develop a novel controller which combines feedback linearization with variable structure. The system is decoupled and linearized by using the nonlinear linearization theories of input-output feedback. On this basis, by applying the variable-structure theory, we design the inner loop for velocity control and pitch control for ensuring the system for robustness. Combining the inner loop control with the outer loop PID control for flight-altitude, we build the entire flight control system. Simulation results show that this method is feasible and useful.
