Study on flexible universal logics intelligent control

In the face of the complex controlled object, environment and control task, the intelligent control methods show the greater advantage and broader development prospects than the traditional ones. The logic foundation of current intelligent control methods are mainly classical logic and fuzzy logic. The classical logic is only suitable for describing the completely opposite binary world. Fuzzy logic admits the flexibility of true value. However its proposition conjunctions are rigid. So, the flexibilization problem for the intelligent control model is studied here. And a flexible intelligent control method based on universal logics is proposed. Because its logic foundation admits the flexibilities of true value, proposition conjunctions, quantifier and the reasoning, the control method can simulate the human´s control methods better. The successful control experiments for typical linear and nonlinear systems prove the validily of proposed method.
