Why would you use PID controllers if you can use NN directly? Insisting on PID is rigidifying part of your control setup. It's forcing NN to partially not learn the optimal control. It's a bit like transformers for LLMs. If we could train raw NN in reasonable time it would outperform transformers. We are currently using transformers just because it makes learning of large models feasible not because it's somehow the best architecture for predicting language. The same way PID is something that sort of works if you lack computing power to create better control schemes.
