Add dead zone ratio to PID controller for noise suppression (#1032)
* Add dead zone ratio to PID controller for noise suppression - Introduced `dead_zone_ratio` parameter in the PID controller to suppress noise from small deviations in error rates. - Updated the `calculate_p_value` method to implement dead zone logic, allowing for more stable control responses. - Enhanced tests to validate the behavior of the dead zone in various scenarios, ensuring it does not impede recovery while effectively filtering noise. * Added experiment tests * Refine dead zone logic in PID controller - Updated the handling of the dead zone in the PID controller to allow full signal response above the dead zone, improving control accuracy. - Adjusted comments for clarity regarding the purpose of the dead zone in noise suppression. * Added experiment results
