one of the challenges of using renewable energy is low voltage level in this sources. A suitable solution for solve this problem is to use DC-DC converters to increase the output voltage level of these sources. In recent years, due to the good characteristics of Z-source converters, these converters have been widely used in renewable energy systems. Due to changes in input voltage and load, the need for a control method to regulate the reference voltage is inevitable in renewable energy systems. In this research, a controller based on an Interconnection and Damping Assignment-Passivity-Based control (IDA-PBC) with appropriate internal connection and damping matrices is considered to control the DC-DC Z-source converter. The presented controller has zero steady-state error in tracking the DC reference voltage. The mentioned controller is designed with average state model; therefore, it guarantees stability in a wide range. This controller is robust to reference voltage, load and input voltage changes. Some simulations have been performed in MATLAB/Simulink to evaluate the efficiency and robustness of the proposed method.
