Smart textiles improve device connectivity for HMIs, medical applications

Researchers from the National University of Singapore (NUS) have incorporated conductive textiles called metamaterials into clothing to connect several wearable devices at once, which could be used for human-machine interfaces (HMIs), health monitoring and other medical applications.

Figure: Rate-predictive control (RPC) is inherently adaptive (think naturally self-tuning) to changes in process gain. In the top graph, process gain is 1.0, while in the bottom graph, process gain is 2.0. Control performance remains “perfect,” with no change to RPC tuning parameters. Courtesy: APC Performance LLC

Advantages of RPC and limits of model-based control

Part 3: Rate-predictive control, an alternative algorithm to proportional-integral-derivative (PID) and model-based control, can provide single-loop control. See three RPC advantages and two model-based control limitations.
