ADAPTIVE CONTROL WITH FEEDFORWARD COMPENSATION AND REDUCED REFERENCE MODEL

IFAC Proceedings Volumes, 1983
Abstract Two modifications to the standard adaptive model-following control (AMFC) algorithm given in Landau (1979) are described. The first refers to the extension of the algorithm to consider measurable disturbance inputs in a feedforward adaptive fashion.

A Neural Network‐Based Self‐Sensing Embedded Position Control System for Shape Memory Alloy Wire Actuators

Advanced Intelligent Systems, EarlyView.
Shape memory alloy wires exhibit thermally induced phase changes that generate actuation strain and resistance variations enabling self‐sensing. However, hysteretic electromechanical behavior complicates accurate state estimation. This paper presents an artificial in‐based self‐sensing method to reconstruct SMA actuator position in real time, achieving
