Abstract

The invention provides a time varying division method applied to stabilization of a swinging angle of a hanging load of a helicopter. The method includes the following steps: 1), giving a dynamical equation of a helicopter hanging simplified model, and acquiring relevant parameters; 2) establishing a mathematic model for stabilization control of the swinging angle of the hanging load of the helicopter based on the dynamical equation of the step 1, and providing a time varying division question; and 3) designing a solver and performing real-time solution to the time varying division question of the step 2. According to the time varying division method applied to stabilization of the swinging angle of the hanging load of the helicopter, the solver is simple, and the problem of that the conventional static division method occurs an abnormal state during a divide-by-zero situation can be avoided.

Description

technical field [0001] The invention relates to a method for dealing with the problem of stabilizing the swing angle of a helicopter hanging load, in particular to a time-varying division method capable of solving the problem of dividing by zero. Background technique [0002] During helicopter transportation, the motion of the load will exhibit physical characteristics similar to that of a simple pendulum. The load oscillation caused by the movement of the helicopter and external disturbance not only seriously affects the improvement of transportation efficiency, but also has an adverse effect on the flight of the helicopter. If the stable control of the helicopter's hanging load is realized, the transportation efficiency of the helicopter will be greatly improved, the driving pressure of the driver will be relieved, and the safe transportation of the helicopter will be ensured. Therefore, it has very important application value to realize the stability control of the helic...
