The present invention relates to the field of electrical control technology, and an embodiment thereof provides an adaptive control method, device and equipment. An adaptive control method is applied to a hydraulic system including a hydraulic control element using PID closed-loop regulation. The method includes: obtaining detection values of at least one hydraulic factor, where the detection values are used to determine the PID parameters of the hydraulic control element or serve as a feedback signal when the PID parameters of the hydraulic control element are fixed; and the hydraulic control element performs the PID closed-loop regulation under the PID parameters and the feedback signal. The method provided in the embodiment of the present invention has high control precision and is convenient for large-scale application.

Figure 1) An interface device for retrofit installation to a controller of a motorised bed is provided for enabling communication between the controller and a voice command device. In one form, the device includes: at least one connector for connecting with a serial port of the controller; a wireless communications module for wirelessly connecting to the controller and the voice command device; and a microcontroller operatively connected to the at least one connector and the wireless communications module. The microcontroller is programmed to: automatically determine how the controller is configured to communicate; receive a control command from the voice command device, said control command corresponding to a voice command issued by a user to the voice command device; translate the control command into a control instruction compatible with the protocol determined; and transmit the control instruction to the controller to actuate a desired movement of the motorised bed.
