[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] The embodiment of the present invention provides a dedicated controller for a food waste disposer, please refer to Figure 1 , the dedicated controller consists of the following parts:

[0030] It includes: a main controller, a remote control terminal connected to the main controller, a faucet switch control terminal and a motor control terminal;

[0031] Signals are transmitted between the remote control control end and the external remote control; the faucet switch control end controls the switching action and switching time of the faucet; the motor control end is connected to the motor to control the forward and reverse rotation of the motor, and the rotation of the motor drives the grinding disk in the food waste disposer to grind the food waste.

[0032] The working principle of the above technical solution is: the solution adopted in this embodiment is to set up a main controller, and a remote control control end, a faucet switch control end and a motor control end connected to the main controller; signal transmission is performed between the remote control control end and the external remote control; the faucet switch control end controls the switching action and switching time of the faucet; the motor control end is connected to the motor to control the forward and reverse rotation of the motor, and the rotation of the motor drives the grinding disc in the food waste disposer to grind the food waste.

[0033] The beneficial effects of the above technical solution are as follows: the solution provided by this embodiment is used to set up a master controller, as well as a remote control control terminal, a faucet switch control terminal, and a motor control terminal connected to the master controller; the remote control control terminal transmits signals to an external remote controller; the faucet switch control terminal controls the faucet's on / off action and on / off timing; the motor control terminal is connected to a motor to control the motor's forward and reverse rotation, and the rotation of the motor drives the grinding disk in the food waste disposer to grind food waste. Therefore, this embodiment can effectively and rationally link the remote control, faucet switch control, and motor control, improving the efficiency and intelligence of the control.

[0034] In another embodiment, please refer to Figure 2 A timing device is set in the main controller. When the main controller detects that the rotation speed reaches a preset value, the main controller sends a first timing signal to the timing device. The timing device starts timing. When the timing time is up, the timing device sends a first timing completion signal to the main controller. The main controller sends an opening instruction to the faucet switch control end according to the timing completion signal. The faucet switch control end controls the switch of the faucet to turn on according to the opening instruction.

[0035] The working principle of the above technical solution is as follows: This embodiment adopts a solution in which a timing device is provided in the master controller. When the master controller detects that the rotation speed reaches a preset value, it sends a first timing signal to the timing device. The timing device starts timing. When the timing time expires, the timing device sends a first timing completion signal to the master controller. The master controller sends an opening instruction to the faucet switch control terminal based on the timing completion signal. The faucet switch control terminal controls the faucet to turn on and off according to the opening instruction. The preset value can be the rotational speed of the motor during normal operation. Reaching this speed indicates that the motor has started normally.

[0036] It should be noted that this embodiment also provides a solution to ensure the stability of the motor speed and the improvement of anti-interference performance. The disturbance torque value can be calculated based on the speed acceleration. The compensation circuit can be further calculated based on the disturbance torque value, and then the current loop parameters can be determined. The current loop parameters are the current feedback system. Generally, it refers to the method of connecting the output current to the processing link by positive feedback or negative feedback, mainly to improve the performance of the system by improving the stability of the current.

[0037]

[0038] Among them, T L (z) represents the disturbance torque value, z represents the transformation parameter of Z transformation, K t Represents the motor torque constant, I q represents the quadrature-axis current, J represents the sum of the motor moment of inertia and the load moment of inertia, a represents the filter constant, and u(z) represents the sliding-mode switch control function.

[0039] Based on the above formula, the speed and acceleration of the motor can be estimated. Since the calculation error of the sliding mode switch control function is concentrated in the high-frequency area, the use of a low-pass filter can effectively filter out the high-frequency calculation error, thereby avoiding the problem of phase lag caused by the high-frequency calculation error in the motor control system. Therefore, this solution can make the speed of the motor in the normal working state more stable, the speed fluctuation range is smaller, and it has an improved effect on interference performance such as load disturbances. That is, when external interference occurs, the speed balance and current balance can be adjusted in a relatively short time.

[0040] The beneficial effects of the above technical solution are as follows: using the solution provided by this embodiment, a timing device is provided in the master controller. When the master controller detects that the rotation speed reaches a preset value, it sends a first timing signal to the timing device. The timing device starts timing. When the timing time is up, the timing device sends a first timing completion signal to the master controller. The master controller sends an opening instruction to the faucet switch control terminal based on the timing completion signal. The faucet switch control terminal controls the faucet to turn on according to the opening instruction. This embodiment can achieve automatic control.

There is no need to manually turn the faucet on and off, and the faucet switch is controlled through interactive control with the remote control.
