Modal parametric optimization of control laws with special structure

The paper is devoted to particular cases of optimization problems for dynamical systems with scalar control and external disturbance. The aim is to find optimal parameters of an output feedback controller having initially given structure. An admissible set of controllers is determined by the requirement to place the poles of linear closed-loop connection inside desirable regions on the complex left-half plane. Numerical algorithm is proposed to solve the posed problem using special multi-purposes structure of the controller. To show practical applicability and effectiveness of the proposed approach and the benefits of developed methods, the illustrative example of marine autopilot design is presented.
