The paper discusses an S-function implementation using BP neural networks for automatic PID parameter tuning. This method employs backpropagation algorithms to dynamically adjust proportional, integral, and derivative gains through neural network learning. However, the current implementation faces challenges in convergence stability and real-time performance. The approach typically involves designing network structures with input layers for system error signals, hidden layers for feature processing, and output layers generating optimized PID parameters. We anticipate developing more robust solutions that could incorporate adaptive learning rates, improved activation functions, or hybrid optimization algorithms to achieve better control performance and stability.
