Abstract: Gas turbines represent complex multi-system coupled devices exhibiting nonlinear, time-varying, and uncertain characteristics, imposing stringent requirements on control system design. As a fundamental control function throughout the entire load-bearing process, power control critically supports unit load regulation and stable operation, making the development of reliable power control strategies particularly significant. This study addresses the limitations of conventional staged-load power control strategies for small gas turbines, notably their inadequate disturbance rejection capability, by proposing a novel hybrid open-loop/closed-loop control approach. The methodology involves separate design of open-loop and closed-loop controllers, with seamless switching between control modes achieved through a hysteresis-based switching strategy, thereby significantly improving both unit maneuverability and load process stability. Experimental validation on actual turbine units confirms the strategy's feasibility and effectiveness, demonstrating enhanced disturbance rejection performance, with the approach having been successfully implemented in practical engineering applications.
