主 题:System identification tracking control input saturation
摘 要:Machine learning-based data-driven approaches have greatly improved system identification capabilities and facilitated the application of model-based control ***,tech-niques such as neural networks require significant amounts of training data and have limited generalization *** overcome this problem,we employ the sparse identification of nonlinear dynamics with control(SINDYc)for system identification,which considers both system states and control *** on the identified system,we design the controller using the backstepping control *** order to make the algorithm more practical in real-world scenarios,we introduce an input saturation compensation system into the controller ***,we apply a command filter into the method to avoid deriving a virtual control signal and reduce the computational complexity of the *** stability analysis,the proposed control algorithm ensures that the tracking error in the system is ***,we verify the effectiveness of the proposed SINDYc-Backstepping framework by conducting simulations using a single-link robot arm.
