Research at the Aalen Actuators & Sensors Lab focuses on the model-based development of innovative actuator systems. The core area of our work is the development of actuators based on shape memory alloys (SMA). We start from the experimental characterization of shape memory wires. From the measurement results, mathematical models are derived that represent the complex non-linear behavior of shape memory wires. The models are used in the development and control of shape memory actuators for various applications, but also for analyzing the behavior of actuator prototypes.
