On Convergence of Extended State Observer for a Class of MIMO Uncertain Stochastic Nonlinear Systems
IEEE Access, 2018 Extended state observer (ESO) is the key part of active disturbance rejection control, a new control strategy motivated and developed highly from PID's model-free feature. In this paper, both constant gain ESO and time-varying gain ESO are proposed for a
