An Algorithm to Build Delayed Control for Mobile Wheeled Robot Taking Into Account Wheel Slip
The article deals with a tracking task for mobile robot with three rollercarrying wheels taking into account wheel slip and delay in feedback structure. To solve this task, the author suggests applying continuous control with saturation which represents a combination of relay control and quickly changing linear control. The article also cites an algorithm for control parameters and maximum value of system delay. Tracking task, delayed control, rollercarrying wheels, wheel slip.

Synthesis of Control for Mechanical Systems With Unknown Inertia Matrix Taking Into Account Delay in Feedback Structure
The article is devoted to trackingtask solution for mechanical systems with unknown inertia matrix and variable delay in feedback system. It justifies a continuous law of control with saturation, gives an algorithm for controlparameter finding. The applied approach is based on the use of Lyapunov vectorfunction with vectornorm components. This method allows the estimation of the maximum value of delay in the system and domain of initial displacements from a trajectory being tracked.
A twolink manipulator on a mobile base is given as an example in the article. Tracking task, delayed control, mechanical system with unknown inertia matrix, lyapunov vectorfunction.

Control With Saturation in Tracking Task for Mechanical Systems Subject to Delay
The article deals with the task of tracking for mechanical system taking into account delay in the structure of feedback. It proves continuous law of control with saturation, which is an approximation of relay control. The approach is based on the use of Lyapunov vectorfunction with components in the form of vector norms. A mobile robot with threeroller wheel is considered in the article as an example. Mechanical system, tracking task, control with saturation, delay, lyapunov vectorfunction, matrix norms, mobile robot with roller wheels.
