Influence of quantization errors on control quality of main steam temperature control systems of power stations;

The power network integrated automation brings up more and more high requestabout control quality of the coordination control system in the monoblock.

To solve the problem of ever-declining control quality of conventional PID controller resulted from fixed control parameters,ideal variation relationship between control parameters and control objects was studied,and thus a non-linear function obtained,and a non-linear PID controller built up,of which the parameters was tuned with NCD module Simulink toolbox.

The simulation results of a single-degree-of-freedom AMB system show that the proposed controller has good disturbance rejection ability;and other control performance is also much superior to the traditional PID controller.

According to all kinds of mismatch between the practical model parameters and predictive model parameters, this paper respectively gives out theory analysis and example simulation, which prove that the improved Smith predictor has better control performance than the traditional Smith p.

Application of HACCP system in production and sanitary quality control of cooling flesh;

Talking about the quality control point of friture of instant noodle;

The critical consideration is attached to rust removing,application of anti-corrosion and fireproof coatings and its quality control.

It takes us much time and care to monitor quality control samples of BOD5.
