Simulation analysis of intelligent anti-tremor spoon control system based on BP-PID

Taking the smart anti-tremor spoon for Parkinson's disease (PD) as the research subject, this study analyzes and establishes the dynamic model using the Simulink platform. It simulates hand tremor signals of PD patients at different Hoehn-Yahr stages (H-Y stages) during meal consumption, proposes the BP-PID double closed-loop system for anti-tremor control, and compares it with a traditional PID. The experimental results demonstrate that the optimized PID controller achieves a tremor suppression rate of over 96.7% and 96.0% for early-stage and late-stage PD patients, it exhibits strong anti-tremor ability and robustness in the face of load variations.
