Abstract:
A novel approach is proposed to suppress bounded exogenous disturbances in linear
control systems using a PI controller. The approach is based on reducing the original problem
to a nonconvex matrix optimization problem. A gradient method for finding the controller’s
parameters is derived and its justification is provided. The corresponding recurrence procedure
is rather effective and yields quite satisfactory controllers in terms of engineering performance
criteria. This paper continues a series of the author’s research works devoted to the design of
feedback control laws from an optimization point of view.
