Example Embodiment

[0022] See figure 1 Shown is a circuit block diagram of a preferred embodiment of the present invention. As shown in the figure, the present invention includes a resolver signal pattern capturing unit 1, a deviation corrector 2, an observer 3, a tracking filter 4, a trigonometric function signal generator 5, and an integrator 6. Among them, the signal capture unit 1 is used to output the sine sin and cosine cos signals of the resolver rotation angle, and form the angle of the signal and the tracking angle simulation and Signals, which are respectively input to the deviation corrector 2, which generates a deviation signal

[0023] The observer 3 is a PI-type observer, which receives the deviation signal generated by the deviation corrector 2 Then, the angular velocity signal ω is generated, and the angular velocity signal ω is output to the tracking filter 4, where the tracking filter 4 is a multi-dimensional digital filter, which forms an analog angle in the tracking filter, ...

Abstract

Provided is a pure software resolver angle acquiring and signal processing method. The method comprises the following steps: a resolver excitation signal is generated by a signal synchronous acquisition unit; rotation angle sin and cos signals synchronously induced by a resolver analyze and process the signal to form sin (1) and cos (1) signals; a deviation signal delta (1) is generated from the sin (1) and cos (1) signals and simulation tracking angle sin and cos signals; a corner speed signal omega is generated by the deviation signal delta (1) through a viewer; the simulation angles of sin (2) and cos (2) signals are formed by the corner speed signal omega through a tracking filter and are compared with the sin (1) and cos (1) signals so as to form a resolver angle acquiring control loop for generating single-turn signals; and multi-turn angle signals and the resolver are generated through an integrator and a differentiator so as to facilitate the control and measurement of orientation and speed of a machine tool or an automatic machine. The method provided by the invention facilitates the integration of a modern digital control system and improves the precision and speed of the system.

Description

technical field [0001] The invention relates to a method of angle acquisition and signal processing of a pure software angle resolver, especially an angle acquisition and signal that can output multi-turn angle signals to improve the precision and dynamics of machine tools or automatic machines. Processing device. Background technique [0002] General high-speed and precision machine tools or automation machines, the high-dynamic servo drive assembly used requires high-accuracy and dynamic angle feedback components to control and measure the orientation of the transmission system in order to maintain the machine tool or automation machine accurate operation. In the existing calibration and testing methods, the general angle feedback components are incremental encoders (encoder), which are sensitive to the working environment or temperature changes based on the photoelectric principle, and require high mechanical assembly, so their accuracy and speed Relatively uncertain, t...
