Survey of singularly perturbed control systems: theory and applications;

The stable range of singularly perturbed maglev system parameter was studied based on cascade PID controller.

A kind of singularly perturbed boundary value problem is investigated.

The singularly perturbation model is an efficacious method to solve this proble.

According to the dynamic behavior of reactor-heat exchanger networks featuring multi-time scales, two sub models were derived respectively in two time scales using the method of singular perturbation modeling: a model about energy balance in fast time scale, and a model about material balance in slow time scale.

Then a singular perturbation method was adopted to solve the freezing problem, the analytical solution was obtained.

A slow subsystem and a fast subsystem are separated based on the singular perturbation method,which the sliding mode control method and H infinity control method are adopted in each subsystem respectively.
