Abstract:
In this paper, a new approach for dynamic modeling and the controller design of an omniwheel mobile platform with respect to high dynamic requirements is proposed. Compared with the previous articles, the tire model and the electrical machines are taken into account. The entire dynamic model is derived as a semi-explicit form of descriptor systems, which treats the tire forces and the torques of the electrical machines as fictitious inputs. It is possible to parameterize all the state variables, the constraints and inputs with the corresponding structure coordinates and their derivatives analytically. Due to the property of differential parameterization, the design of the decoupling controller can be achieved easily by transforming the overall system in Brunovsky normal form. By introducing additional coupling conditions, the electrical machines can work in optimum condition with respect to energetic aspects to generate the desired torque for driving.
