Overview

Artificial intelligence enables accurate self-sensing position control in shape memory alloy actuators, indicating improved performance.

Key Points

  • The aim is to develop an artificial intelligence-based system for accurate self-sensing in shape memory alloy actuators.
  • Developed a neural network combining recurrent and simple neurons.
  • Used electrical power and SMA wire's resistance as inputs for real-time position estimation.
  • Implemented the neural network on a microcontroller for embedded control.
  • Achieved root mean squared errors of 0.028 and 0.021 mm in position estimation.
  • Validated accuracy against a sensor-based control system using a 2 mm displacement range.
