Abstract
The report describes the design of an algorithm which can be used for automatic
controller tuning purposes. It uses an on-line parameter estimator and a pole assignrnent
design method. The resulting control law is formulated to approximate a
proportional-integral (PI) industrial controller. The development ofthe algorithm
is based on the delta-operator, Some implementation aspects such as covariance resetting, dead zone, and signal conditioning are also discussed. Robust stability and
performance are two issues that govern the design approach. Additionally transient
and steady state system response criteria are utilized from the time and frequency
domains. The design work is substantiated with the use of simulation and real plant
tests.
