Abstract
An actuation system to achieve soft landing and the control method thereof are provided. A soft landing is achieved via an open loop control of an electromagnetic actuator. The actuation system includes a control unit, wherein the control unit controls the electromagnetic actuator. The control unit does not rely on sensor data regarding a position of an armature to achieve the soft landing. As the actuation system achieves soft landing via the open loop control of the electromagnetic actuator by the control unit, a use of the sensor data is not needed.
Claims11
An actuation system, comprising
- an electromagnetic actuator, wherein the electromagnetic actuator comprises a body, at least one coil, and an armature to convert an electrical energy into a mechanical energy,
- a control unit, wherein the control unit applies a voltage signal to the electromagnetic actuator on the at least one coil for an open loop control of the electromagnetic actuator to achieve a soft landing, wherein
- a first portion of the voltage signal is applied to energize the at least one coil,
- a second portion of the voltage signal is applied after the voltage signal is closed and an admittance time is finished to generate the soft landing of the armature (3) and,
- the second portion of the voltage is applied for a period of time shorter than a period of application of the first portion of the voltage signal.
