Description

technical field [0001] The invention relates to a floating-point DSP-based servo motion control device, which is mainly used in the field of angular motion control of a turntable system used in inertial device testing, so as to realize the control of various motion forms such as angular position, angular velocity, and angular vibration. Background technique [0002] The input and output of the servo motor include the acquisition of the position feedback information of the motor and the output of the control quantity. At present, the feedback type of the motor is mainly focused on the encoder method of quadrature pulse feedback, and the servo control of the motor generally uses a fixed-point DSP chip dedicated to motor control as the CPU of the controller. This type of DSP has quite a lot of peripherals. Including digital encoder interface and PWM interface, there are also some A / D and D / A interfaces, which are more convenient for motor control applications in general occasio...
