The invention discloses a multi-rotor aircraft motor tension linearity measurement device and its control system and method, comprising a tension sensor, a lightweight pull rod, a motor to be tested and a bracket, the bottom end of the light pull rod is connected to the tension end of the tension sensor, The top of the light pull rod is connected with a mounting seat, and a fixed ring is set on the light pull rod; a motor base is provided at the bottom of the motor to be tested, and a paddle is installed on the top of the motor to be tested; the motor base can be fixed on the mounting seat; The tension linearity is measured and analyzed to form a linearity analysis curve; programming developers can perform linearity compensation at each point according to the linearity analysis curve, so that the linearity of the motor is close to linear, which is convenient for the post-control of the aircraft; any PWM value can be given to the motor. Observing the magnitude of the pulling force at this point can help the hovering stability of the aircraft to be adjusted; the invention has the advantages of simple structure, low cost, short debugging period and high accuracy of debugging parameters, which brings convenience to users.
Description
technical field [0001] The invention belongs to the field of mechatronics, and in particular relates to a multi-rotor aircraft motor tension linearity measurement device and its control system and method. Background technique [0002] The motor pull linearity of multi-rotor aircraft is not good, and the control amount applied to the same pull point is different for the same batch of motor linearity, which brings difficulties to programmers. Traditional motor linearity analysis tools It is impossible to systematically analyze the linearity of each pull point of the motor, and it is impossible to correct the linearity of the nonlinear motor. Contents of the invention [0003] Purpose of the invention: The present invention provides a multi-rotor aircraft motor tension linearity measurement device and its control system and method to solve the poor linearity of the motor tension in the prior art, and the linearity of the same batch of motors at the same tension point The amo...
