Venayagamoorthy, Senior Member, IEEE Real-Time Power and Intelligent Systems Laboratory Missouri University of Science and Technology, Rolla, MO 65409, USA. pm33d@mst.edu gkumar@ieee.org Abstract— A new adaptive control strategy based on [5] present different control strategies based on the multi-level Artificial Immune System (AIS) for a DSTATCOM in an electric inverter topologies of shunt compensators. Attempts have been ship power system is presented in this paper. DSTATCOM is a made to make the controller robust by applying sliding mode shunt compensation device, which can be used to improve the control strategy as in [6] and [7]. But, these control strategies power quality during the pulse power requirements in a naval are not adaptive to the system dynamics. Also, most of the shipboard system. The role of DSTATCOM controller is very conventional control schemes of DSTATCOM have several PI important to meet this objective. In this paper, the DSTATCOM controllers. The tuning of PI controllers is a complex task for controller parameters are first tuned by Particle Swarm the systems having power electronics equipments. In order to Optimization (PSO) technique, so that it can provide innate overcome these problems, Computational Intelligence (CI) immunity to common system disturbances. Then, these opti
