In this paper, a concurrent design method for properly stabilizing normal decentralized compensators of descriptor decentralized systems with direct control feedthrough is proposed. This concurrent design method gives the same order for each compensator among all the control stations, and the shortcoming of the sequential design method before having very high compensators' orders for large scale systems is overcome. So the design method obtained here is very significant both in theory and in practice.

It is acknowledged that intuitive decision making is based on the determination of suitable reference points. Therefore, it is necessary to explore the selection mechanism of reference points. The authors categorized and defined four types of reference points: lower valued reference points, higher valued reference points, match typed reference points and context dependent reference points. The authors also discussed possible biases produced by unsuitable using of these types of reference points.

Reduced space SQP algorithm for the optimization of large scale process systems are studied in this paper.
