摘要：

The hydro-turbine governing system (HTGS) holds a crucial position in maintaining overall stability and security of hydropower stations. HTGS characterized by intricate dynamics involving strong coupling, nonlinearity, and non-minimum phase behavior, is responsible for regulating the frequency of the hydropower system. This article proposes a predefined-time fractional-order sliding mode controller (PTFOSMC) aimed at improving the frequency stability of the nonlinear HTGS, accounting for both internal disturbances and external noises within a predefined time. Input/output feedback linearizatio...
