A quadcopter is a type of UAV (Unmanned Aerial Vehicle) that is widely utilized across various fields due to its versatility. However, maintaining the stability or attitude of a mini quadcopter is a challenging task, primarily because of its nonlinear system characteristics and sensitivity to external disturbances. To address this issue, this study implements a Cascaded Sliding Mode Control (CSMC) method as a robust nonlinear control solution. The control system is designed in a two-layer structure: an outer loop that regulates the orientation angles, and an inner loop that controls the angular velocities. This system is implemented on an STM32F401RCTx microcontroller.
Experimental tests were conducted in an indoor environment using a test bed to observe the system’s response under both undisturbed conditions and external disturbances. The results demonstrate that the system is capable of maintaining stable attitude control, exhibiting fast rise times, limited overshoot, and consistent angle stability even in the presence of disturbances. Therefore, the CSMC method proves to be an effective solution for attitude control of STM32-based mini quadcopters.
