Model-free control

摘要: ''Model-free control'' and the corresponding ''intelligent'' PID controllers (iPIDs), which already had many successful concrete applications, are presented here for first time in an unified manner, where new advances taken into account. The basics of model-free control is now employing some old functional analysis elementary differential algebra. estimation techniques become quite straightforward via a recent online parameter identification approach. importance iPIs especially iPs deduced from presence friction. strange industrial ubiquity classic PID's great difficulty tuning them complex situations deduced, sampling, their connections with iPIDs. Several numerical simulations include infinite-dimensional systems. They demonstrate not only power our intelligent but also simplicity them.
