Abstract

An adaptive internal model control (IMC) framework is proposed in this article for infinite impulse response systems. The innovation in this study stems from the relaxed assumption that the controller needs to know a priori the system order. To bypass this restriction, a lattice filter identifies the system's order as well as its reflection coefficients. Within the IMC structure, a lattice-based controller is utilized in the forward path in cascade with a low-pass detuning filter. The controller self-configures its structure according to the estimated system order, while the filter's bandwidth increases as the identifier estimates more accurately the system dynamics.
