This paper proposes the optimal two-degree-of- freedom proportional-integral-derivative-accelerated (2DOF- PIDA) controller design for the liquid-level system based on the modern optimization by using the modified bat algorithm (MBA). The MBA is the new modified version of the original bat algorithm (BA) developed to improve its exploration and exploitation by using the random number drawn from a Lévy- flight distribution as well as new loudness and pulse emission rate functions. Results of the 2DOF-PIDA controller designed by the MBA are compared with those of the one-degree-of- freedom proportional-integral-derivative (1DOF-PID) and 1DOF-PIDA controllers designed by the MBA. As results, the liquid-level controlled system with the 2DOF-PIDA controller designed by the MBA can provide very satisfactory responses superior to that with the 1DOF-PID and 1DOF-PIDA controllers designed by MBA.
