چکیده
Abstract In the practical application of modular multilevel converters (MMC), with improvement voltage level and power, more submodules (SMs) need to be cascaded in order obtain levels different amplitudes approximate sinusoidal output voltage. The acquisition submodule capacitor is premise MMC control, which makes system many sensors monitor sub-module reduce number weaken jitter, this paper collects current signal bridge arm combined switching uses saturation function set as sliding mode observer (SMO) estimate simulation results show that has good robustness accuracy.

Robust Controller Design Based on Sliding Mode Observer in The Presence of Uncertainties and Actuator Saturation
This paper studies the design of a robust output feedback controller subject to actuator saturation. For this purpose, a robust high-gain sliding mode observer is used to estimate the state variables. Moreover, the combination of Composite Nonlinear Feedback (CNF) and Integral Sliding Mode (ISM) controllers are used for robust output tracking. This controller consists of two parts, the CNF part...

متن کاملOutput integral sliding mode control based on algebraic hierarchical observer
The problem of the realization of integral sliding mode controllers based only on output information is discussed. The implementation of an output integral sliding mode controller ensures insensitivity of the state trajectory with respect to the matched uncertainties from the initial time moment. In the case when the number of inputs is more than or equal to the number of outputs, the closed lo...
متن کاملFault Reconstruction Based on Sliding Mode Observer for Nonlinear Systems
This paper presents a precision fault reconstruction scheme for a class of nonlinear systems involving unknown input disturbances. First, using the coordinate transformation algorithm, the disturbances and faults of the system are fully decoupled. Therefore, it is possible to eliminate the influence of disturbances to the system, namely, better disturbances robustness. On this basis, the design...
