Embodiment

[0128] According to the multi-parameter optimization control method of the dynamic electromagnetic loading force of the water lubricated bearing in this embodiment, the target loading force is set, the readings of the torque speed sensor, the piezoresistive load cell, the two pairs of eddy current sensors and the load system controller are collected and the signals are transmitted To the load controller, the load controller reads the sensor readings and performs average processing respectively to obtain the average value of the loading force measurement of the piezoresistive load cell signal. Excitation current measurement average value of the current sensor signal Average value of the speed measurement of the torque speed sensor signal Determine whether the non-contact electromagnetic loading force matches the set value. If it matches, each sensor will continue to repeat the above process; block, the load controller adopts the three-dimensional data path tracking algorith...

Abstract

The invention discloses a dynamic electromagnetic loading force control system for a water lubricated bearing, which comprises a pair of non-contact electromagnetic loading devices, a load device driver, an eddy current sensor, a torque rotating speed sensor, a piezoresistive force transducer, a load controller and a current regulator, and is characterized in that the load controller is connected with a database stored in a server hard disk; the method has the control effect of higher precision under the condition of long-time operation. The invention further discloses a water lubricated bearing dynamic electromagnetic loading force multi-parameter optimization control method, data collected in actual operation are read, an output current effective value is obtained through a path planning algorithm and a sliding mode control algorithm by calculating a correction value of a coordinate and designing a sliding mode surface form, the control precision is guaranteed, and meanwhile the dynamic electromagnetic loading force of the water lubricated bearing is optimized. The overshoot is reduced, and the dynamic performance of a load system is stabilized.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment state monitoring, in particular to a multi-parameter optimal control system for dynamic electromagnetic loading force of a water-lubricated bearing, and a multi-parameter optimal control method for the dynamic electromagnetic loading force of a water-lubricated bearing. Background technique [0002] Electromagnetic loading devices have gradually been widely used in the condition monitoring of mechanical equipment. The electromagnetic loading device can provide non-contact load. Compared with the contact-type non-contact electromagnetic loading device, it avoids problems such as friction and vibration, and has a better application effect. In the process of dynamically applying the electromagnetic loading force by the electromagnetic loading device, the loading force will be unstable due to factors such as shafting speed, axis displacement, magnetic field changes, etc., which will have ...
