Özet

Obtaining the parameters for PID controllers based on limit cycle information from the process in a relay controlled feedback loop is, in many cases, an acceptable practical procedure. If the form of the plant transfer function is known, exact expressions for the limit cycle frequency and amplitude can be derived in terms of the plant parameters, so that their measurements, assumed error free, can be used to calculate two unknown plant parameter values. in the literature to date the solutions have been considered for stable or unstable first order plus dead time (FOPDT) or second order plus dead time (SOPDT) plant transfer functions. This paper reports on exact parameter estimation for an SOPDT plant transfer function with the further addition of a , stable or unstable, zero by a single relay feedback test.
