Abstract :
Aircraft control is often exposed to disturbances and uncertainties. Accomplishing safe and secure flight requires robust controls. The well-known robust methods usually suggest large in size controllers. In this paper, a PID sized controller (μ-PID) is designed where both the robust frequency domain merits, observed by the robust techniques, and the time domain desires contribute. The performance index weights are appropriately set to match the intended goals. The optimization process is conducted using particle swarm optimization (PSO) technique. The H∞, μ synthesis and the μ-PID designs are used for a multi-input multi-output (MIMO) flight lateral control. The controlled variables are the roll angle ϕ and the sideslip angle β. The numerical simulation demonstrates that the proposed method with lower sized controller can yield performances better than what the robust methods such as the H∞, μ synthesis designs succeed.
