In this paper, a comprehensive control system for precise motion control and trajectory tracking of Four Mecanum-Wheeled Mobile Robots (FMWMRs) is presented. The proposed approach addresses issues including nonlinearities, uncertainties, and external disturbances by combining a fuzzy logic controller for orientation co...

Flexible joint robot manipulators (FJM) exhibit high nonlinear dynamics and coupling effects, which make their control a challenging task. This paper proposes a fractional order PID (FOPID) cascade control strategy for a 2DOF FJM. The controller performance is compared with that of a sliding mode controller (SMC) under...

The proposed framework provides a clear methodological foundation for learning-based inverse dynamics modelling and its integration with robotic control systems, and future work will extend the framework to real-time implementation on physical robotic systems.
The Pendubot is a nonlinear underactuated system with two rotational degrees of freedom and a single actuator, making stabilization a challenging problem for intelligent and nonlinear control methods. Reliable balancing control is important for evaluating control strategies under both simulation and practical hardware...

Low-cost geared DC motors are widely used in mobile robotics and embedded mechatronic systems; however, their control remains challenging due to dead-zone nonlinearities, friction, low encoder resolution, motor asymmetry, and supply voltage variations. Biological organisms routinely perform motor control in the presenc...
