Abstract

The invention discloses a pneumatic position servo controller based on a DSP. The pneumatic position servo controller comprises DSP module, a signal modulating circuit board module, a controller standard interface panel and a control box; the DSP module is connected with a signal modulating circuit board, and is fixed on the controller standard interface panel; a control panel is fixedly mounted in the control box, and provides external power supply input, an air pressure signal, a displacement sensor signal, CAN communication and a simulation debugging standard interface; the standard interface is connected with a circuit joint or a sensor joint of the signal modulating circuit board in the control box; the DSP acquires signals to perform the control strategy operation; and control signals are output to transfer to an external actuator via the controller standard interface panel. The pneumatic position servo controller is fast in actuation speed, high in system timeliness and complex in operation of servo motion control strategies, adopts a CAN bus to communicate, can perform the multi-master and multi-slave communication, is convenient to perform the colony cooperative control, and uses an embedded microprocessor to achieve low system power consumption and compact structure.
