Embodiment 1
[0015] Embodiment 1: The gigamagnetic system used in the active control of structures usually includes two parts: the giant magneto-actuation system and the controlled structure. The giant magnetic drive system includes a controller and a driver, which are used to drive and control the vibrating structure (that is, the controlled structure) according to the instructions issued by the controller. The driver is a giant magnetostrictive actuator, and its structure is shown in the attached figure 1 shown. The giant magnetostrictive actuator comprises a casing 1, a coil 11 arranged in the casing 1, a giant magnetostrictive rod 2 arranged between the coils 11, a guide that is connected with the giant magnetostrictive rod 2 and extends out of the casing 1. pole 3. The shell 1 is composed of shell side walls 8 and upper end caps 9 and lower end caps 10 at both ends thereof. The guide rod 3 is connected with the casing 1 through the pre-tightening bolt 4 , and a disc spring 5 is ins...

The invention relates to a giant magnetostrictive system in structural active control. The giant magnetostrictive system comprises a giant magnetostrictive drive system and a controlled structure driven by the giant magnetostrictive drive system to act. The drive system comprises a controller and a driver. The giant magnetostrictive system further comprises a force sensor and a displacement sensor, wherein the force sensor is used for detecting output force of the driver and converting the output force into force sensing signals, the displacement sensor is used for detecting displacement generated by the controlled structure and converting the displacement into displacement sensing signals, the output of the force sensor is fed back and connected to the driver, and the output of the displacement sensor is fed back to the controller and is fed back and connected to the driver. The giant magnetostrictive drive system further comprises a compensator used for compensating for deviation generated in the loading process of control signals output by the controller, wherein the input of the compensator is connected with the controller, and the output of the compensator is connected with the driver. By means of the giant magnetostrictive system, the complex interaction among multiple links is considered, and the multiple links are integrated and connected; consequently, the accuracy of the whole giant magnetostrictive drive control system can be further improved, and the control effect is further improved.
Description
technical field [0001] The invention relates to a gigantic magnetostrictive system composed of a giant magnetostrictive driving system and a controlled structure, which is applied in the active control of structures. Background technique [0002] With the rapid development of structural vibration control technology, the accuracy of structural control has become the bottleneck of the development of structural vibration control, especially for micro-vibration, there are higher requirements for the accuracy of structural control. Usually, the precision of control is improved by improving the precision of the driver itself, and the complex interaction of the whole system is often ignored, and these dynamic factors often restrict the control precision, which makes the theoretical control precision deviate from the actual control precision. Contents of the invention [0003] The purpose of the present invention is to provide a giant magnetostrictive system that is applied in the...
