Monitored Control System

In this paper, we study the production of 1,3-propanediol in fed-batch culture with coupled feed of glycerol and alkali. On the basis of the numerical solution to an optimal control problem subjected to a multi-stage nonlinear dynamical system, we propose a realizable optimal feeding strategy. Correspondingly, an automatic control system is designed for the fermenter, which involves the designs of control circuit, software flow control and computer monitored control system. This contribution successfully achieves a goal of combining a mathematically theoretical analysis with an automatic control design in the laboratory.

Weighted Values

With the development of the electronic technology, people have proposed higher requirements for the service quality on elevator, and the optimal elevator dispatching has developed a typical multi-objective optimal process. This paper analyzes both the advantages and the disadvantages of artificial immune algorithm and gradient descent algorithm, optimizes artificial immune algorithm, then proposes a novel optimal hybrid algorithm; at the same time, uses this hybrid algorithm in the elevator group control system combined with Pareto solution set. Making a comparison between the hybrid algorithm and the standard artificial immune algorithm, it’s clear that this hybrid algorithm has certain feasibility and superiority, and to some extent, has improved the overall performance and service quality of the elevator group control system. This paper has provided a new method and a new thought on determination of the multi-objective weighted values in the elevator group control system.
