Review on research progress in process control
过程控制研究的一些进展

The performance of feedback control systems is needed to be more strict and more accurate,and there will be new challenges to the continuously emerging new materials and new processes in process control fields.A review is presented to summarize recent research developments on control of nonlinear distributed parameter processes (e.g.,material microstructure,particle-sized distributions,and fluid flow),analysis and control of biological systems and biomedicine processes,integrated urban wastewater treatment monitoring systems,and some future research directions.The methodology and integrated tools needed to solve such complicated control problems are discussed,including theory and practice of the process system engineering,the control systems integrated physics devices with communication network.Finally,it is pointed out that attention should be paid to some fields where control applications are weaker at present by control researchers.
