Nonlinear control systems represent a critical area of study wherein the relationship between inputs and outputs is not directly proportional, resulting in complex and often unpredictable dynamics. In ...

The proposed controller for ballbot devices enhances the adaptability to dynamic environments via self-learning and self-adjusting characteristics. Ballbot is a unique kind of robot with great ...

The ballbot is a unique kind of robot with great mobility and possesses the ability to go in all directions. Obviously, ...

Optimal solutions to Markov decision problems may be very sensitive with respect to the state transition probabilities. In many practical problems, the estimation of these probabilities is far from ...

We develop test statistics to test hypotheses in nonlinear weighted regression models with serial correlation or conditional heteroscedasticity of unknown form. The novel aspect is that these tests ...
