In this paper, coherence function estimation for parallel tracks from road measurements is studied. A two-stage scheme is proposed. In the first stage, the measurements are de-trended and periodic components are removed. An autoregressive moving-average (ARMA) model is fitted in the second stage to the vector-valued residuals derived from the left and right track measurements by using a recently developed...
Among the issues discussed in this article the main problem concerns a neuro-fuzzy system (ANFIS) for controlling a mobile robot, which is considered one of the methods of artificial intelligence. The first part discusses the classical approach to control a mobile robot. Firstly, a mathematical model was presented describing the kinematics of a two-wheel mobile robot, which was later used for the...
The paper is focused on the control algorithm for anti-slip control of the independent car axle. The axles were powered by independent electric engine with torque controller controlled by CAN bus and torque demand. The main control unit is cRIO / LabVIEW with CAN bus.
The potential advantages of a modern active suspension system are recognized for race cars, on road cars or even for great series cars. Beside the passenger ride comfort, the control of the vehicle vertical acceleration directly affects the road holding. In the case of passive suspension models, the car structure is optimized in initial stage of design, taking into consideration the spring stiffness,...
Crossing over obstacles or riding up in steep terrain is still not completely solved problem in wheeled-mobile robotics. This paper describes a concept of four-wheeled mobile robot with unique patented wheels made of rotary segments. Rotation of segments changes the surface of wheels from normal wheel for movement on roads or flat ground to wheels for movement in terrain, over obstacles or upstairs...
