![]() This ensures the transient performance of altitude control of the powered parafoil. ![]() A fractional sliding surface is introduced to the backstepping control. Backstepping control is employed to regulate the inclination angle to follow the desired value. An LESO is used to estimate the total disturbance and form an inner-loop compensation. ![]() Next, uncertainties and disturbances are considered as a total disturbance. The problem of altitude control is converted to the issue of angle control. First, the dynamics of a powered parafoil is derived in the longitudinal plane using its inclination angle. This paper presents a method of altitude control of the powered parafoil with uncertainties and disturbances based on sliding-mode backstepping control combined with a linear extended state observer (LESO).
