Abstract

The invention discloses a two-freedom-degree helicopter simulator for researching a control rule and relates to a helicopter simulator. By virtue of adopting the two-freedom-degree helicopter simulator, the problems of low bandwidth of control signals, time delay of the system, poor safety, inconvenience in maintenance and larger occupied space in the existing helicopter simulator for researching the control rule are solved. The two-freedom-degree helicopter simulator comprises a base, a vertical pipe, a gear, a vertical shaft, a barrel-shaped supporting seat, a first code disc, a swinging rod, a second code disc, a hollow shaft and two motors, wherein the vertical pipe is fixed on the base; the upper end of the vertical pipe is fixedly provided with the barrel-shaped supporting seat; the second code disc is arranged in the vertical pipe; the gear is arranged on an output shaft of the second code disc and is meshed with gear teeth processed on the vertical shaft; one side of the barrel-shaped supporting seat is provided with the first code disc; an output shaft of the first code disc is rotatably connected with one end of the hollow shaft; the swinging rod penetrates through the hollow shaft and is detachably connected with the hollow shaft; the two ends of the swinging rod are respectively provided with one motor. The two-freedom-degree helicopter simulator disclosed by the invention is used for researching the control rule and detecting a system identification algorithm.

Description

technical field [0001] The invention relates to a helicopter simulator, in particular to a two-degree-of-freedom helicopter simulator for studying control laws. Background technique [0002] The helicopter simulator with rotor is a commonly used control object in the control discipline, and it is an ideal experimental platform for studying control laws. Helicopter simulators with two degrees of freedom, three degrees of freedom or six degrees of freedom have the characteristics of nonlinearity and strong coupling, and due to the existence of propellers in the equipment, aerodynamic factors are introduced into the system. So many scholars in the field of control are keen to study this system and apply the designed control law to the system. [0003] There are quite a number of rotor-type experimental systems at home and abroad, and two types of experimental platforms have been summarized. One is a model helicopter based on the field of model aircraft, the main part is a mod...
