Tunable liquid prism is important member of liquid optical devices, and its advantage over
solid material prism lies in the non-mechanical tunability. Therefore, it is of great value for …

The hysteresis characteristic can significantly decrease the control accuracy of magnetic
shape memory alloy actuator. To describe the hysteresis between input signal and the …

This paper presents an actuator based on magnetic shape memory alloys (MSMAs) suitable
for precise positioning in a wide range (up to 1 mm). The actuator is based on the spring …

Magnetic shape memory (MSM) actuators belong to active material technologies with a high
energy density and outstanding field-strain relation. Large-scale multivariate field-stress …

Self-sensing techniques are a commonly used approach for electromagnetic actuators since
they allow the removal of position sensors. Thus, costs, space requirements, and system …

As a new type of intelligent material, magnetically shape memory alloy (MSMA) has a good
performance in its applications in the actuator manufacturing. Compared with traditional …

This papers deals with PI and PID control of second order systems with an input hysteresis
described by a modified Prandtl-Ishlinskii model. The problem of the asymptotic tracking of …

Active materials are a class of material which react to an external stimulus such as
temperature, photons, magnetic field or electric field. These stimuli cause some properties of …

This paper is focused on hysteresis modeling in actuator with magnetic shape memory alloy,
briefly MSMA. MSMAs are new group of active materials which change shape in external …

Smart materials, such as thermal or magnetic shape memory alloys, provide interesting
characteristics for new solid state actuators. However, their behavior is highly nonlinear and …
