Abstract: |
Time-delays (dead times) are
found in many processes in industry. Time-delays are mainly caused by the
time required to transport mass, energy or information, but they can also be
caused by processing time or accumulation. The contribution is focused on a
design of universal digital algorithm for control of great deal of processes
with time-delay. This requirement is successfully satisfied with digital
Smith Predictor based on Linear Quadratic (LQ) method. A minimization of the
quadratic criterion is realized using spectral factorization. The designed
algorithm is suitable for control of stable, unstable and non-minimum phase processes.
The algorithms for control of individual processes influenced by external
disturbance were verified. The program system MATLAB/SIMULINK was used for
simulation of designed algorithms. |
