Power system is a complex giant system, security and stability operating of which is significance for economic construction and social stability of country. But every control theory has its strong points and shortage, so there is some more difficulty for adopting single control theory or method to solve technical problem of complex control system. The paper taking asymptotically tracking and disturbance...
Coordinated control system is a strong coupling, multiple-input and multiple-output system. Load and the main steam pressure control are interdependence, mutual constraints; it is non-linear dynamic characteristics of unit; boiler side emerge large delay. Therefore it is very difficulty of obtaining a satisfactory control effect for conventional control strategy. In order to improve the coordination...
The linear time-invariant systems of equivalent one another in algebra represent mathematical models of a same physical system described in different state vectors. Algebra equivalent observer (AEO) is derived from the non singularity of state space presentation in linear system, which is a very important concept in control theory. For the rapid calculation of parameters of AEO, which have effect...
The contradiction between speediness and stability is a salient problem of control system especially when the system is with character of time-varying parameters and big-inertia. It is hard to be solved perfectly either by classical control or modern control or intelligent control. The integrated control scheme and concept of generalized intelligent control (GIC) is proposed in this paper. The state-space...
From the engineering observational fact and require, and based on the conception and theory of algebra equivalent observer, this paper presents the conception of algebra proportion analogical observer, which use betaG1(s) as the state observer of G(s), where G1(s) is the linear transform of G(s), meanwhile, G1(s) is pure rational common fraction. Then this paper uses mathematical method to analyze...
The stabilization is the target of a control system designing and the chief condition to improve control performance. The system stability proving is an important work of control theory research. And it has guidance meaning to control system design and application. This paper aim at control strategy of state feedback based on incremental function observer(IFO-KDeltax) merging with conventional PID...
The correctness of mathematical model that is as basis to research work will have a direct impact on the practical application of boiler-turbine coordinated control system. So selecting a correct mathematical model as the reference of control strategy and its controlled object of simulation test is an important process to acquire success in practice. Various modeling methods all should be guided by...
