This paper concerned with the design method of state and disturbance observers for discrete-time nonlinear systems. An augmented model is constructed by assuming that the estimated disturbance is in state-space variable form. A sufficient condition for the existence and convergence of the robust observer is proposed in terms of linear matrix inequality (LMI). The gains of the state and disturbance...
In this paper, the design of nonlinear observer-based dynamic controller for Nonlinear Networked Control Systems (NNCS) will be presented on the assumption that there exist packet loss between the sensor and the controller and between the controller and the actuator. Two different linear function of a stochastic variable satisfying a Bernoulli random binary distribution will represent the existence...
This paper concerns with the strong stabilization for a typical example of MIMO under-actuated robots called the Pendubot, which is a two-link under-actuated planar robot with a single actuator at the First joint. First, a study of the existing of blocking zeros is presented to check for strong stabilization condition. Then the paper presents a design method for observer-based dynamic strongly stabilizing...
