This paper presents a network controlled Linear Parameter Varying (LPV) control framework for a hydro power plant. The linearized plant dynamics is assumed to be controlled via remote controller operations over communication networks. The controller action to hydro plant and the plant output to controller input signals are assumed to be transmitted over different networks with a bounded network delay and associated packet drops. As the network delay is modeled as a Pade approximation, the control system signal transmissions over the networks are modeled as an LPV system such that the accurately received packets and lost packets are used as the real-time time-varying parameter that can be measurable in future periods. The communication network LPV characteristics are expressed in terms of a polytopic parameter-dependent model to efficiently characterize the overall network operations for received and lost packages, and the associated LPV controller synthesis perspectives are detailed. The networked controlled LPV controller synthesis and simulation results clearly demonstrate the effectiveness of the framework for networked control system delay and packet loss issues on stability and performance.
