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...
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...
Boiler super-heater steam temperature control object is generally with characteristic of parameters slow time variable, big inertia and larger time lag. Using the IFO-KDeltax and PI state observer for reference, the concept of "Incremental PI Function Observer in Broad Sense" (IFO-PI/BS) is presented. Theorem on stable conditions of control system based on the IFO-PI/BS is proved by mathematical...
Even if the transfer function G(s) of a control system is given, but the practical observer should be designed according to G1(s) that is a equivalent form of the G(s) because of some uncertain reason. Based on the algebra equivalent concept of linear system theory, the mathematical definitions of three types of algebra observer are presented, those are named as full dimension algebra equivalent state...
