Classical Control

Aiming at the stability control of the automatic control system, this paper proposes a root locus correction scheme. By establishing the mathematical model of the control object and using the root locus correction method in the classical control theory, the design of the control system is completed. The simulation experiment of the control system is carried out in the MATLAB environment, and the key points of the scheme are summarized. The simulation results show that the scheme not only successfully achieves the stability control of the system, but also meets the expected performance index, which fully proves its correctness and effectiveness.

The Stability

Soakage agent in glass fiber production is critically, the stability of its quality is directly related to the stability of the glass fiber quality. According to the characteristics of the soakage glass in fiber agent production process, this paper is mainly introduced the multi-sensor information collection for the soakage agent process parameters, and is proposed to use PLC programming, PID control and fuzzy control harmony methods to achieve the real-time automatic control preparation process of the soakage agent in adding water of amount, adding oil of amount, temperature control, liquid level control, viscosity test and many other parameters . The practical application of the automatic control system is reliable, accurate, real time.

The Stability

The work is aimed at solving the applied problem of developing an automatic control system for the evaporator using the principle of D-partition. Since there is always uncertainty in real problems, the solution of the problem of synthesis of the control system is reduced to the synthesis of a robust regulator. As a result, the area of robust stability of the object was obtained and an array of PI controller settings was formed, which ensures the stability of the object in the entire range of uncertainty.
