In the defense industries, robot technology and the use of robots for defense system are growing rapidly. A robot with Remote Control Weapon System (RCWS) needs a stable Direct Current (DC) voltage for accelerating its movement, reading the data precisely, and controlling the DC-motors accurately. In this paper we did a feasibilty study of a robust buck converter operated in Continuous Conduction Mode (CCM) with Sliding Mode Controller (SMC) for hybrid diesel-electric drive. SMC is a non-linear control that changes the system dynamic of a non-linear system by employing discontinue control signal (equivalent control) and continue control signal (switching part). It forces the system to lie on the sliding surface for the system in the normal operation. SMC is used to make the buck converter generating stable output voltage to support such robot with a hybrid diesel-electric drive. SMC acts as Pulse Width Modulator (PWM) which triggers the buck converter. From the simulation results, we concluded that SMC successfully plays its role to make the buck converter maintaining the stability of the required voltage level for the RCWS robot. © 2019 IEEE
