چکیده مقاله:
This paper presents the speed control of separately excited dc motor (SEDM) using armature voltage control method based foraging strategy. Armature voltage speed control system is done using state feedback controller with parameters tuned using bacterial foraging optimization (BFO) technique. The motor angular speed and armature current are sensed and feeding back (state feedback controller) for comparison with its reference values to generate control signal in order tocontrol armature voltage as well as the motor speed. The proposed design problem of speed controlleris formulated as an optimization problem. Bacteria Foraging Optimization Algorithm (BFOA) is employed to search for optimal controller parameters. The SEDM mathematical model is used because it's more reality to the actual plant rather than linear transfer function model in the control design andstudies and give more accurate results. BFO technique improves the controller performance by choosing optimal parameters values which leads to improve the transient and steady state specifications. The proposed method is very efficient and could easily be extended for other global optimization problems.
