Abstract
This application relates to the field of drive technologies, and discloses a control method, a device, and a readable storage medium. In one example method, when detecting that at least one actuator line in a shape memory alloy (SMA) actuator is disconnected, an electronic device may control, through at least one non-disconnected actuator line, a carrier of the SMA actuator to move relative to a fastening part.
Claims20
A control method, applied to an electronic device, wherein the electronic device comprises a shape memory alloy actuator, a fastening part of the shape memory alloy actuator is connected to a carrier through N actuator lines, one end of the actuator line is connected to the carrier, the other end of the actuator line is connected to the fastening part, and when the actuator line contracts, the actuator line drives the carrier to move relative to the fastening part;
- and the method comprises:
- detecting a first operation of a user, wherein the first operation indicates the carrier to move in a first direction;
- and
- when L actuator lines in the N actuator lines are disconnected, and a direction of a resultant force, acting on the carrier, of K actuator lines upon contraction in N–L non-disconnected actuator lines is the same as the first direction, driving, by using the K actuator lines, the carrier to move in the first direction, wherein N, K, and L are integers.
A non-transitory readable storage medium, wherein the readable storage medium comprises instructions, and when the instructions are executed by an electronic device, wherein the electronic device comprises a shape memory alloy actuator, a fastening part of the shape memory alloy actuator is connected to a carrier through N actuator lines, one end of the actuator line is connected to the carrier, the other end of the actuator line is connected to the fastening part, and when the actuator line contracts, the actuator line drives the carrier to move relative to the fastening part, the electronic device is enabled to implement:
