Embodiment Construction

[0076] At present, the temperature drift effect of the driving force of actuators with oil bearing motors, such as actuators suitable for housing applications, on the one hand, as mentioned above, by changing or limiting the environment in which the actuators with oil bearing motors are located temperature. On the other hand, by applying more expensive Field Vector Control (FOC) schemes etc. to temperature compensate actuators with oil bearing motors. The way of changing or limiting the ambient temperature virtually limits the scope of use of the actuator of the oil-impregnated bearing motor. Generally speaking, most of the actuators with oil bearing motors are relatively low-cost low-end actuators such as actuators suitable for housing applications, and the way of adding hardware devices will greatly improve the performance of actuators with oil bearing motors. cost.

[0077] The actuator mentioned in the embodiment of the present invention may be an actuator with an oil-im...

Abstract

The invention provides a temperature compensation method of an actuator and the actuator, the temperature compensation method of the actuator comprises the steps that a reference duty ratio is obtained, and a pulse width driving signal with the reference duty ratio can drive the actuator to output a target driving force at a reference temperature; the current environment temperature is obtained; apre-obtained compensation relationship at different temperatures is obtained; and according to the compensation relation corresponding to the environment temperature and the reference duty ratio, thecompensated duty ratio under the environment temperature is calculated, and the pulse width driving signal with the compensated duty ratio is used for driving the motor so that the actuator can output the target driving force. According to the scheme, temperature compensation can be carried out on the actuator.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a temperature compensation method for an actuator in the field of heating, ventilating and air-conditioning and the actuator. Background technique [0002] The actuator is a commonly used device in the field of heating and ventilation, which is used to drive the valve placed in the fluid passage to a fully open, partially open, or fully closed position. The actuators used to control the valves in the heating and ventilation system can precisely make the valve open to the desired position. figure 1 An exemplary control relationship between a typical valve and an actuator is shown. Such as figure 1 As shown, the valve 102 is placed in the passage of the heating pipe 10, and the opening of the valve 102 can be used to adjust the flow of hot water in the valve heating pipe. The actuator 101 is connected to the valve 102, and the actuator 101 converts the el...
