Stability, robustness and oscillation of differenct uncertain time-delay systems are analyzed. Synthetical time-delay control schemes are proposed, including robust stabilizing control, variable structure control, robust dissipative control and so on. Industrial time-delay system model are established based on the theorematic results and industrial requirements. Pratical control algorithms and APC-software are developed and applied to practical process successfully.
