Abstract: |
In technical practice often occur
higher order processes when a design of an optimal controller leads to
complicated control algorithms. One of possibilities of control of such
processes is their approximation by lower-order model with time-delay (dead
time). The contribution is focused on a choice of a suitable experimental
identification method and a suitable excitation input signals for an
estimation of process model parameters with time-delay. The further
contribution is design of an algorithm for digital control of high-order processes, which are
approximated by second-order model of the process with time-delay. The
designed control algorithms are based on a predictive control strategy. The
controller’s algorithm uses the digital modification of the Smith Predictor (SP). The
program system MATLAB/SIMULINK was used for simulation verification of these
algorithms. |
