Problems solved by technology

At this time, the speed detection and control of the motor need to be carried out at the same time. It is necessary to detect and control the motor displacement in real time, that is, to control the size of the eccentricity. Therefore, relying on the motor output shaft or output device to detect the speed can no longer meet the radial variable motor control. Requirements, new detection methods and control methods are required to meet the application requirements of radial motor speed control

Abstract

The invention belongs to the field of hydraulic radial plunger motor rotating speed measurement and particularly relates to a radial plunger motor rotating speed measuring and control system and method based on double-angle induction. According to the measuring and control system, the swinging angle of a plunger of a radial plunger motor is acquired by fixedly installing two angle sensors; and anacquired voltage signal is analyzed, and then a real-time rotating speed and the rotating direction of the radial plunger motor can be acquired. Measuring is easy and convenient, and stable and reliable; and the sensors are arranged on a shell of the radial plunger motor. Practicability and convenience are achieved, and installing is not limited by space; and a PID control algorithm is adopted, real-time control over the rotating speed of the radial plunger motor is achieved, the control responding speed is high, stability is good, and the measuring and control requirement on the rotating speed of the radial plunger motor in engineering can be met.

Description

technical field [0001] The invention belongs to the field of hydraulic motor rotation speed measurement, and in particular relates to a radial piston motor rotation speed measurement control system and method based on double-angle induction. Background technique [0002] Radial piston motors have a series of advantages such as small size, large displacement, good low-speed stability and large output torque. It has a wide range of applications, such as vehicle drive, rotary drilling head rotation and so on. There are many parameters to measure the performance of the motor, and the working speed is an important indicator, which can be used to feed back the operating parameters of the working device, and can also provide a control basis for the control system. In the process of engineering construction, it is necessary to measure and control the speed of the motor in real time according to the construction quality specifications to ensure the smooth development and quality con...
