Abstract: A finite-time control method is proposed for the CE150 helicopter with multiple
inputs, strong coupling and nonlinearity. By considering the helicopter system as a cascaded
one and performing coordinate transformation, a finite time nested saturation method is
used to stabilize the two subsystems in finite time. The closed-loop system achieves global
uniform finite-time stabilization by verifying the forward uniformity. Simulation shows
effectiveness of the system, faster convergence, and better robustness.

Key words: CE150 helicopter, finite time control, cascading system, nested saturation
