Tolerance Theory

In order to guarantee the safe operation of train and improve the operation efficiency, a kind of failure-safety control strategy of system is proposed based on the dual-redundant control mechanism. The paper analyzes the function requirement of train automatic speed control, researches on the design principles and methods of the architecture design of the dual-redundant control system which is based on the tolerance theory, analyzes the control strategy of the system running state translation, uses Markov model to analyze the system reliability and safety. Finally, a series of simulation analysis are performed, and the results show that the system has good reliability.

Linear Addition

A simple, linear, noninteractive model of the reflex control of blood pressure was developed to demonstrate that simple linear addition of the responses of the baroreceptor reflexes can produce observations that appear to have resulted from a redundant control system. Our analysis indicated that common experimental paradigms such as hemorrhage with sequential reflex ablation, which are often used to evaluate reflex interactions, can be simply interpreted. Complex nonlinear interactions need not be postulated to explain data that appear to indicate a redundant control system.
