چکیده مقاله
Microturbines are widely used in distributed generation, combined heat and power CHP systems, and grid support applications, where precise speed/frequency regulation is essential under highly variable loads and significant thermodynamic parameter uncertainties This paper proposes a low order H∞ robust controller for single shaft microturbines that systematically addresses both exogenous load disturbances and endogenous parametric uncertainties e g , variations in compressor/turbine efficiencies, heat losses, and rotational inertia The controller is synthesized using mixed sensitivity loop shaping combined with μ analysis to guarantee robust stability and performance across the entire operating envelope Closed loop simulations under severe load steps, rapid frequency demands, demonstrate excellent disturbance rejection and setpoint tracking with minimal overshoot and settling time Comparative results show that the proposed H∞ governor considerably outperforms conventional PID controller in terms of robustness, transient response, and steady state accuracy, making it highly suitable for practical microturbine applications in modern power systems
