Abstract:
Abstract: This assessment represents a Multi-Input-Multi-Output-Proportional-Integral-Derivative (MIMO-PID) controller for load frequency balance issues. The objective of load frequency control is to minimize the transient deviations in area frequency and tie-line power. To improve the robustness of the system the transfer function H8 norm is used. So the proposed technique is known as PIDH8 controller. The LFC problem is articulated as a H8 SOF (State Output Feedback) control approach to attain the decentralized robust MIMO-PIDH8 controller. H8 controller is used here for accomplishing stabilization with definite performance. The optimization difficult is formulated and iterative LMI algorithm is used to tune the control parameters of the MIMO-PIDH8 controller. The simulation results show the proposed strategy is very effective and guaranteed good robust performance against the parametric uncertainties and load changes.
