Abstract: |
Concise complete controller design with
simulations for a laboratory circuit heating plant with feedback delays is the
aim of this contribution. The particular steps of the design include a
mathematical modelling summary of then plant,
introduction of relevant algebraic tools, robust controller design and
tuning, its discretization and rational simplification.
The plant model contains internal delays, thus, it is infinite-dimensional. A special ring of stable and proper quasipolynomial
functions represent the main algebraic mean for controller structure
design. A possible range of adjustable controller parameters is then limited by
using the robust stability and performance analysis. Their
eventual values are consequently obtained by simulations of control responses.
A discretization of the resulting controller is
suggested and a method for its rational simplification is verified by
simulations in MATLAB® and Simulink®. All the
obtained results are promising for a practical implementation of the
presented approach. |
