Two surge interactive and non-interactive tank systems are taken as examples of multi-level tank system. Due to the dynamic level changes of the two-tank system, various control techniques are intended to regulate the level by controlling the liquid infl ow quantity. In addition to that, disturbance eff ect is considered to get better step response for the tuning of Proportional Integral Derivative (PID) controller by using meta-heuristic algorithm. In this paper, Proportional Integral Derivative (PID) controller design analysis is carried out by using Feed Forward (FF) control, Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Bubble Net Whale Optimization Algorithms (BNWOA). BNWOA is used to tune the PID controller to reduce constrains of two tank system and obtain the optimal control is proposed. The transfer function of the two-tank system with step input for various control algorithms such as GA, PSO and BNWOA are observed using MATLAB Simulink and M-script. From the analysis, better performance such as reduced constrains and optimal control can be obtained from BNWOA. Then steady state analysis is made and the simulation results are presented at the end.
