Eitelberg introduced a useful method to recover system performance when a direct tuning of the PID’s parameters was prohibited in 1987 [1]. Our work herein proposes the use of adaptive tabu search (ATS) [11] to optimally tune the input-weight factors according to Eitelberg’s. We illustrate the effectiveness of our proposed method via two motor control(More)
A new hybrid tabu search (HTS) method for solving assembly line balancing problems is proposed in this paper. The tabu search (TS) method is combined with the genetic algorithm (GA) to identify and provide solutions for assembly line balancing problems. With the proposed HTS method, the TS method can well address the number of tasks assigned for each(More)
This paper presents a convergence proof of the adaptive tabu search (ATS) algorithms. The proof consists of two parts, i.e. convergence proof of all interested solutions in a finite search space, and that of searching processes of the ATS algorithms to the global minimum. With the proposed definitions and theorems, the proofs show that the ATS algorithms(More)

A 2-mass rotary system is widely used in industrial applications. Torsional resonance, however, usually appears in such the system. This article presents an attempt to suppress torsional resonance and to improve the performance of a system. With two-degree-of-freedom (2-DOF) configuration, feedforward and feedback compensators are used. The former provides(More)
