• Theoretical analysis to prove convergence performance and noise-learning capacity.
• Validation through time-dependent numerical examples and a robotic control application.

Main Results:

• The ANLDNS model effectively solves TD-ECQO problems in the presence of noise.
• The noise-learning mechanism enhances model robustness by adapting to noise variations.
• Theoretical proofs confirm the model's convergence and noise-learning capabilities.

Conclusions:

• The proposed ANLDNS model offers a robust and practical solution for noisy TD-ECQO problems.
• The model demonstrates superior performance compared to existing state-of-the-art methods.
• The application in redundant robot control highlights its real-world applicability.
