Design of Nonlinear Controllers

Area: Engineering

State feedback controllers are widely used in real-world applications. These controllers require the values of the state of the plant to be controlled. An observer can provide these values. For nonlinear systems there are some observer design methods which are based on differential geometric or differential algebraic concepts. The application to non-trivial systems is limited due to a burden of symbolic computations involved. The authors propose an observer design method using automatic differentiation.
