Objectives: Design and implementation of PI/PID controllers with parameter optimization using different techniques for MIMO systems. Methods: Biogeography Based Optimization based Proportional Integral Derivative (BBOPID) and investigating the robustness of the BBOPID technique applied to boiler turbine unit. Design of a Coordinated PID (CPID) Controller and tuning the CPID parameters using Particle Swarm Optimization (PSO), Bacteria Foraging (BF) and BBO techniques are discussed. Findings: The design of controller is done by using the performance index of Integral Square Error (ISE). Results show that BBO controller gives better performance for both servo and regulatory responses. Application: The electric power is generated using steam driven turbo generators, where the steam is produced by drum boilers as as practices base, reuses and stores the best practices.
