Problems solved by technology

The electrode segmentation process is added in the space division multiplexing decoupling method, which is not very convenient for cylindrical or tubular or multi-layer piezoelectric transducer elements; most magnetostrictive elements are rod-shaped, so the space division multiplexing decoupling method Applicable two-way transducing materials and shapes have certain limitations

Embodiment Construction

[0015] The specific implementation modes and examples of the present invention will be described in detail below in combination with the technical scheme and the accompanying drawings.

[0016] The physical basis of the present invention is the electromechanical two-way transduction theory of functional materials, as shown in Figure 1 . When the bidirectional transducing element 1 is used as a sensor, the force F or velocity v of the mechanical port is converted into the voltage U or current I of the electrical port; when the bidirectional transducing element 1 is used as an actuator, the voltage U or current I of the electrical port is converted into Force F or velocity v at the mechanical port. Usually, only one direction of energy conversion is used, and at this time, the device is used as a sensor or an actuator alone. In the present invention, the bidirectional transducing element 1 is used as both an actuator and a sensor. The problem to be solved is how to separate the...

Abstract

The invention belongs to measuring and controlling technique filed of electromechanic system, relates to realizing method and control system based on self-apperceive performer of double-direction electromechanic transducing material. Time division multiplexing decoupling and control system of self-apperceive performer adopts double-direction transducing element, using switching sequence control circuit to control double-direction transducing element as sensor or performer, when the double-direction transducing element is as the sensor, it used sensing switch, when the double-direction transducing element is as the performer, it used executing switch, it uses discharging switch to discharge the double-direction transducing element, the three switches are conducted or closed under control of switch sequence control circuit. The invention decreases volume and weight of electromechanic system, and makes structure controlled integrated and micromated, decreases difficulty of craftwork and installation; it is controlled in parity, increases stability of control. It fits for structure libration initiative control, system identification and health diagnosis, especially fits for flexible structure whose volume and weight are limited.

Description

technical field [0001] The invention belongs to the technical field of measurement and control of electromechanical systems, and relates to a method for realizing the functional integration of sensors and actuators based on bidirectional electromechanical transducing materials, that is, a method for realizing self-sensing actuators and a control system. Background technique [0002] Whether it is for traditional electromechanical systems or recent microelectromechanical systems, implementing measurement and control usually requires actuators and sensors at the same time. The actuator generates displacement or force to complete the desired control action; the sensor measures physical quantities such as displacement or force, and the sensor is inseparable in both open-loop monitoring and closed-loop control. Generally speaking, the technical route to build a control system is to use independent sensors and independent actuators. The disadvantage of this method is that it is no...
