Outline of Final Research Achievements

In this study, we have developed direct control system design methods based on input and output data in which we utilize partial structure information of a plant without using any mathematical models of a plant. In particular, we consider control systems with plants where only the existence of nonlinearities such as dead-zone, hysteresis, saturation, and backlash is known, but their detailed properties are unknown. For such control systems, we have proposed several controller tuning methods that can provide better control performance than the conventional methods. Moreover, we have developed an online controller tuning method by applying an adaptive algorithm to the standard offline controller tuning method. We also have developed a controller tuning tool which can be used on Microsoft Excel.
