- •
A nonlinear model based active nose landing gear shimmy damping system is proposed.
- •
Torsional free play and electromechanical actuator dynamics are taken into account.
- •
A novel optimization procedure called Population Decline Swarm Optimization is proposed.
- •
Two probabilistic models for plant uncertainties are proposed.
- •
Stochastic robustness analysis is used to assess the controller robustness.
