The conventional tuning cannot respond to the performance criteria of a system comprehensively and flexibly, yet the numerical optimization methodologies, such as genetic algorithm and simplex, have shortcomings on strategy parameter selection or initial condition sensitivity. This paper propose a novel comprehensive evaluation function concerning system performance, and optimize the PID controller...
This paper considers the design of PID controllers for systems with varying time-delays. Using the concept of jitter margin combined with the AMIGO tuning rule methodology, novel tuning rules that are robust to varying time-delays are derived. In addition, we give an expression for the expected lower bound of the jitter margin as these tuning rules are applied. Extensive numerical evaluations demonstrate...
This paper presents a procedure for robust PID tuning based on a non-convex optimization problem with H2 and/or H∞ performance criteria and regional pole placement. The uncertain system can be represented by polytopic or affine parameter-dependent models. The efficiency of the proposed tuning procedure is illustrated by two examples
