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...
Coordinated control system of thermal power unit is a time-varying, uncertainties, strong-coupling and multi-variable control system. Its control quality is a key to improve the thermal processes automation and achieve power system automatic generation control. In this paper, the non-linear mathematical models of drum-boiler turbine unit and once-through boiler unit are given. Analysis of the conventional...
For overall interests of the entire power system stability, generator units should have faster and more flexible load response characteristics. Due to complexity of dynamic characteristics of controlled object in thermal control field and new problems are caused by large-capacity power generation equipments updated, many difficulties brings out for control system's design and application. According...
The concept of analog flexible fuzzy control is introduced in this paper. It is applied in the boiler-turbine coordination control system and reheated temperature control system. The practical result shows that this algorithm is easy to be realized in project by applying all sorts of existing algorithms in computer system not depending on special fuzzy control module. This algorithm not only overcomes...
The fuzzy-control usually takes the error and the error derivative between the output and the set point of the system as the input of the controller. But from the pure mathematical point of view, the variable and itpsilas every rank derivative of the system can be seen as the each state of the system. This paper shows some limitation of the classical fuzzy-control and brings forward the concept of...
