In this paper sliding mode controllers (SMCs)' techniques are used and investigated for congestion control problem of differentiated Services (Diff-Serv) networks. Robustness against modeling uncertainties and disturbances are major features of sliding mode controller. Chattering phenomenon affects sliding mode congestion control; to overcome this problem, second order sliding mode control (SOSMC)...
Wheeled mobile robots are considered as the most widely used class of mobile robots. This is due to their fast maneuvering, simple controllers, and energy saving characteristics. Two new algorithms for tracking control of these robots are presented in this paper: an adaptive controller and a nonlinear controller. Here, the two algorithms are compared with regarding noise resistance and disturbance...
