摘要

This article concerns the design of linear feedback controllers for the load frequency control loop of a single area power plant. The system is affected by unknown piecewise constant power load disturbances. The control objective is formulated as a robust regulation control problem relying on an augmented state-space description by an integrator applied on the frequency deviation error. The primary controller achieves pole clustering in a prespecified LMI region, while in the sequel it is further enhanced with H-disturbance attenuation properties. In any case, the power load disturbances are rejected due to the integrator, while the transient behavior is determined by tuning the control parameters through a trade-off between performance criteria and actuation authority. Extensive simulation results demonstrate the complexity aspects of the design procedure and highlight the efficiency of the proposed control schemes.
