Relying on the skill and experience of the engineer, traditional method of safety analyses is subjective and may not guarantee the integrity, consistency and correctness sometimes. In this paper, we first summarize the deficiencies in the safety analysis based on the development of V mode. Then we put forward a new model-based method called VT-mode development. The mode discusses the safety analysis...
Based on state-space model, a kind of method of designing inferential predictive control for dual-rate systems is given. The method has preferable robust stability. State estimator is introduced into dual-rate inferential predictive controller based on state-space model to estimate immeasurable state and solve the problem caused by immeasurable state when designing dual-rate inferential predictive...
The steam valve control problem in multi-machine power systems is dealt with. A design methodology of nonlinear large-disturbance adaptive control is proposed by using backstepping combined with minimax method. Considering the case that the boundary of uncertain parameter is known, the nonlinear minimax controller and the parameter adaptive law are designed to make sure that the steam valve system...
The min-max robust control synthesis for uncertain nonlinear systems is solved using Takagi-Sugeno fuzzy model and fuzzy state observer. Existence conditions are derived for the output feedback min-max control in the sense of Lyapunov asymptotic stability and formulated in terms of linear matrix inequalities. The convex optimization algorithm is used to obtain the minimum upper bound on performance...
The reaction discussed in this paper is a complicated, multi-phase-catalyzed batch reaction to produce phenyl-pyretic acid by double carbonylation of benzyl chloride. In order to industrialize the production process, a significant engineering problem is to study the operation and control of this batch process. The first stage of study in this paper is to process the experimental data, then to build...
