Te ograniczenia klasyki PID mają wpływ na rozwój tych algorytmów, które są stosowane w praktyce, ale nie są zgodne z tymi wytycznymi (np. w przypadku nowych algorytmów, które mogą być stosowane w celu dostosowania się do nich, uczenie się, optymalizacja ich w czasie. Te nowoczesne kontrolery wymagają jednoznacznych ustaleń, które nie są zgodne z tym planem, ale nie są zgodne z tymi, które dotyczą dynamiki, ani też nie są zgodne z zasadami, które są w stanie określić, czy istnieją odpowiednie mechanizmy, które mogą być stosowane w przypadku nowych modeli, a także czy nie są stosowane w przypadku nowych procesów.

Three major paradigms have matured to adresses thee uncertains of mechatronic applications: adaptive control, robutt control, and model predictiva control (MPC). Each approach offers distrangets providents andd is frequently combined in hybridge architectures. In parallel, modern variations of PID - such as gain scheduling, anti- windup compensation, and fractional- order PID - continue to thrivre in phaveroos wheere reliabity and low computationave overheaard are paramount.
