## Abstract This contribution presents an application of a selfβtuning digital PID controller for process control modelled by __Ξ΄__βmodels. The process is identified by the regression (ARX) model using the recursive leastβsquares method (RLSM) with LD decomposition and applied directional forgettin
The constraints on the PID gains, which are derived from the H norm performance index by discretization of the frequency, are convex or concave depending on frequencies. This problem is a non-convex problem, and a new method of approximating these constraints as adequate linear inequalities is propo
