Zinc oxide whiskers production process is considered as the research object in the paper.After analyzing the relationships between gas parameters accessed to the oxidation furnace and the whiskers quality, the gas distribution control system is researched and designed according to the request of the main factors?the oxygen content and the gas flux.At first,the paper propose a framework for the structure of the control system,and summarized its features;then,according to a given mathematical model，we control oxygen content and flow in the Zinc oxide whiskers production process,with using of feedforward decoupling control algorithm and incremental PID control algorithm. Applications use MCGS configuration software and Siemens PLC S7-300 series of the STEP 7 software development. MCGS configuration software uses one of the development of the control system monitoring software, control algorithms and carried out in the MATLAB simulation; PID algorithm uses Siemens PLC S7-300 series of the STEP 7 software development. This implementation of the production of zinc oxide whisker valve automatic control syst
