The article presents the analysis of the automatic control of the bioethanol production process intended for biofuel. It presents the formulated general concept of the system and the method of designing a closed control system based on the iterative prototyping procedure. The modeling and the simulation were carried out in the Matlab®-Simulink environment. The simulation model of the object was developed based on the experimentally registered characteristics. It has been adjusted, i.e. the compatibility of its behavior with the object it reproduces has been confirmed. Based on the tuned model of the object, a control system model was created, which was the basis for computer simulation which enabled the control algorithm parameters to be established. The final verification of the correct operation of the system was performed with the use of hardware simulation. It was based on entering a negative feedback loop of the virtual control system of the real object elements into the loop. The results of the simulation confirmed the correctness of the adopted design.

This article uses the mathematics method to study in view of boiler zero pollution discharge automatic dosing control and other aspects during the dosing control system model parameter is a variable instead of a constant. If the solution density changes, the object characteristic also along with the change, When the system load will change, can cause for the discharge of water changes, examines the PH value also can change along with it, will cause the controlled member model also correspondingly to change. Because the steam system heat supply pipeline has grown, a successful Canadian medicine circulation needs several minute perhaps several dozens minutes, overall system existence serious lag flaw. In view of the above, we used DDCSRD 3211B dosing system control system to eliminate hysteresis to ensure proper, efficient, energy-saving operation of steam boilers. Zero-effluent dosing system from steam to prevent pollution at the source, the boiler system to environmental decline in the discharge of sewage to zero or close to zero.[

Based on MIMO state feedback linearization, the suspension module control system model had been established, and it completed decoupling between double suspension points. Double-suspension system model is very accuracy for investigating stability property and control algorithm of suspension control system. When magnetic flux signal is taken back to control system, suspension modules antijamming characteristics for resisting suspension load variety and external force interference has been enhanced. Some experiments had been done on CMS04 magnetic suspension vehicle in national mid-low speed maglev experiment field of Tangshan city in China. Therefore, the stable property of double-electromagnet suspension control system has been enhanced.

Vector Control System

In the AC control system, vector control theory is very popular as it makes the AC motor achieve the performance as perfect as DC motor [1]. In the paper, the vector control theory is briefly introduced, and then a vector control system model is builded in the matlab/simulink, and the SVPWM technique is adopted. The results show that the improved vector control sytem of PMSM has a excellent performance.
