Photovoltaic (PV) systems have received a lot of interest because of their sustainable nature and ability to power a wide range of electrical devices. This study focuses on the usage of a photovoltaic system in conjunction to an interleaved boost DC–DC converter to power a permanent magnet DC motor (PMDC). The goal is to efficiently regulate the PMDC motor’s speed and performance using feedback controllers, especially Proportional Integral (PI) along with sliding mode regulate (SMC) techniques. The use of a PV system, which captures solar energy and turns it into electrical power, is important to this project. The interleaved boost DC–DC converter acts as an interface between the PV system and the PMDC motor, ensuring optimal power transfer and efficient utilization of the generated energy. Through this setup, the PMDC motor can be effectively powered and controlled, enabling its operation in various applications requiring precise speed and performance control. To regulate the PMDC motor’s speed and performance, feedback controllers play a pivotal role. The PI controller provides a traditional and durable control method by altering the motor speed depending on the difference between the intended and actual speeds. Furthermore, the SMC controller, which is recognized for its capacity to manage system instabilities and disturbances, improves the motor’s control performance by using a surface that slides to drive the system to the intended state while minimizing mistakes and fluctuations. This work aims to analyze and compare the effectiveness of both controllers, evaluating their performance in regulating the PMDC motor’s response to varying source conditions. Simulation studies and experimental validations will be conducted to assess the controllers’ response.
