摘要：

This paper demonstrates the effectiveness and advantages of the polytopic representation of uncertainties in the operating conditions for the design of damping controllers for power systems. A model with a better physical meaning (compared to other robust control approaches) is obtained, making the controller design simpler and less conservative. An Hinfinity output-feedback design procedure with pole placement constraints is applied. The designed controller is tested, via nonlinear simulations, on a benchmark model of a power system for various conditions of operation. The results of these simulations show the controller is able to provide damping for strong inter-area oscillations, over the entire range of operating conditions.
