Abstract

This paper presents a hybrid control system for an articulated tracked mobile robot designed for complex, uneven terrains, combining linear and non-linear control techniques. The system employs advanced modeling of the robot's kinematics, dividing the system into two subsystems: the tracked mobile platform and the articulated system. The articulated system is modeled in 2D, focusing on the front and lateral sides. A global control structure integrates the effects of the three models, providing separate control signals for each. Next, the control system consists of three controllers: two tracking controllers and one stabilization controller. The first tracking controller, based on Backstepping, manages trajectory tracking in the X-Y plane for the mobile platform by controlling position in X, Y, and yaw. The second tracking controller, based on gain scheduling, controls the lateral model's position in Z and pitch. A proportional stabilization controller minimizes roll angle changes in the frontal model. The hybrid control system is validated through simulations and real-world implementation. The trajectory tracking error, settling time, and disturbance response were evaluated, with satisfactory results showing robust and precise navigation in dynamic environments. This work offers a systematic approach to control design and evaluation for articulated tracked robots, bridging theory and practice.
