Robotic systems are well-known to be highly nonlinear processes due to their complex kinematics. The identification of the corresponding system dynamics plays an important role in obtaining an adequate model which is especially hard under changing parametric circumstances. Furthermore, precise knowledge of the state is crucial for a large variety of control tasks. Sparse sensor setups make these problems more challenging due to significant noise impact. For designing an efficient and robust algorithm, an integral transform approach is proposed exploiting the robotic system structure. Specifically, the Modulating Function Method is introduced in the context of multi-body systems for fixed-time parameter and state estimation. An adaptive observer structure is presented in order to give an impression of the general methodology and the related research questions.

Abstract
Robotic systems are well-known to be highly nonlinear processes due to their complex kinematics. The identification of the corresponding system dynamics plays an important role in obtaining an adequate model which is especially hard under changing parametric circumstances. Furthermore, precise knowledge of the state is crucial for a large variety of control tasks. Sparse sensor setups make these problems more challenging due to significant noise impact. For designing an efficient and robust algorithm, an integral transform approach is proposed exploiting the robotic system structure. Specifically, the Modulating Function Method is introduced in the context of multi-body systems for fixed-time parameter and state estimation. An adaptive observer structure is presented in order to give an impression of the general methodology and the related research questions.
