A precision method for optimizing the reliability of a redundant control system and its application

The precision method for optimizing the reliability of a redundant control system with single or multiple constraints is investigated. This method is presented in an easy way. Starting from the physical concept for the least cost and the most benefit in engineering design, two criteria and a basic principle for optimizing the reliability of a control system with single constraints are obtained. For a multiple-constraint problem only one active constraint can be found in general or sometimes a few active constraints. All the other constraints are nonactive and can be discarded without any trouble. Once the ideal solution is obtained, it is then rounded to integral numbers.<<ETX>>
