“…One can cite as an example the works of Keel and Bhattacharyya (1997) and Keel and Bhattacharyya (1999), in which a linear programming approach was used to provide necessary conditions on the fixed order controller design for robust stability of the closed loop systems. In Cunha et al (2016), the design of a robust controller via linear programming is presented in comparison to a conventional design technique applied to the position control of a motor DC. In both works, only linear programming approach is used to solve the optimization problem proposed for optimal tuning of the controllers parameters.…”

This paper presents the design of a proportional-derivative controller (PD controller) by means of the theory of polynomials with interval roots, and applies them to the problem of robust pole placement technique for an interval system represented by a DC motor. It is formulated a optimization problem by Linear Programming approach integrated with the Chebyshev theorem, which incorporates additional constraints on the system and desired performance parameters and allow the designer to find the controller parameters that place closed-loop poles within desired intervals for plants with parameter uncertainties. The design purpose is the minimization of the overall deviation from the desired performance for the closed loop system, as specified by a characteristic polynomials family. For performance comparison, it was designed a classic PD controller and the results shows the good performance.
