Abstract

The invention discloses a control parameter setting method of a speed regulating controller in a speed regulating device of a torque motor; a speed regulating device on which the method is based is composed of a speed regulating order generator, a speed regulating controller, a power driving module, a speed regulating executing mechanism and a speed sensor; the setting method comprises the steps of forming a parameter identifying device of the speed regulating executing mechanism; according to a phase step output response feature of the speed regulating executing mechanism, identifying an equivalent viscous damping coefficient and an equivalent inertia of the speed regulating executing mechanism, dividing the maximal output voltage of the power driving module by the maximal value of a speed regulating order, squaring the obtained quotient, multiplying by 5 times and dividing by the equivalent inertia to obtain an integral coefficient of the speed regulating controller; multiplying the equivalent inertia by the integral coefficient of the speed regulating controller and calculating a square root, multiplying by twice, and subtracting the equivalent viscous damping coefficient from the obtained product to obtain a probability distribution function (PDF) coefficient of the speed regulating controller. According to the control parameter setting method, the controlling parameter of the speed regulating controller is precisely set, and the speed of the torque motor is stably regulated within a wide range.

Description

Technical field: [0001] The invention relates to a method for designing and debugging a torque motor wide-range speed regulating device, in particular to a method for setting the control parameter size of a speed regulating controller in a torque motor wide-range speed regulating device. Background technique: [0002] In the speed adjustment device, torque motor speed regulation is often encountered in many mechanical equipment and weaponry, such as the rotation of the mechanical arm, the rotational movement of the processing equipment, the transmission of the workpiece in the automated production line, the search of the radar antenna, etc. In the torque motor speed control device, the adjusted variable is the movement speed of the mechanical load. In order to obtain the operating speed with lower mechanical load, a reduction device must be arranged between the torque motor and the mechanical load. In this way, not only the cost of the speed regulating device is increased, ...
