The contradiction of speediness and stability is a difficult problem in face of control theory study and control system design at all times. The paper takes time-variable and great-inertia controlled object and its algebra equivalence system as example open out and explain inherence relation produced by character of time-variable to control index. The sufficiency condition of robust Luenberger function...
Complex controlled object request its control system has more and more functions. Every control theory has its strong points and shortage. The paper demonstrates inherence relation of fuzzy control and state feedback control. And balance compatibility and similarities and difference of the two control method at certain conditions. The connotation of generalized intelligent control is take opening...
Dynamic characteristic of supercritical unit is complex. Its control technology is an important research task. This paper presents a mathematical model of coordinated control system controlled objects. For control characteristic of supercritical unit, design a generalized intelligent coordinated control system which made up of classical control, modern control, intelligence control and special measure...
This paper presents a control system design scheme which combined the State Feedback based on the Increment Function Observer with PID, this design scheme has been successfully applied to a 600 MW boiler super-heater steam temperature control system. The control system could be in automation mode continually while the unit quickly changed its load up to 375 MW in succession, and it was taking an excellent...
Based on the compare of two steam feed-water systems of unit 1 and unit 2 in YaoMeng Power Plant, two different Benson once-through boiler feed-water control schemes are designed in this paper, and the state feedback control based on the incremental mode state observer is adopted in both feed-water control schemes. Engineering practice shows that adopting the control scheme of unit 1 and the second...
