The control strategy of self-tuning observer-compensator for time lag systems is discussed, makes it applied to ammonia plant synthesizing section's hydrogen-nitrogen ratio control, which makes a great successes. The qualified rate of hydrogen-nitrogen ratio increased to about 90% from the original 50% or so.
There is a relatively complete style of homogeneous function about the boundary condition in the problem of sure resolution of inhomogeneous boundary condition based on the summarizing of mass former experiences and is proved in this article. It can be very easy to work out the homogeneous function in use of the theorem which is proved in this paper.
This paper has discussed observer-compensator control scheme of time-delay system, and pointed out that this scheme was some sensitive to gain variation of object. It proposed a kind of self-tuning OC (STOC) control scheme. Theoretical analysis and simulation results showed that STOC control scheme had a greater robustness and control quality more than OC control scheme; especially STOC control scheme...
This paper presents a control scheme of intelligent observation compensator on the basis of the control scheme of observation compensator by adding intelligent controller and intelligent switch. Thus the capability of tracking, anti-disturbance and stability of the system are enhanced. Theory analysis and simulation experiment show that the control scheme of intelligent observation compensator has...
The control scheme of modified observation compensator for time delay system is discussed, and makes it applied to ammonia plant synthesizing sectionpsilas Hydrogen-Nitrogen Ratio control, which makes a great success. The qualified rate of hydrogen-nitrogen ratio increased to about 90% from the original 50% or so.
