“…Among these, a particularly relevant solution is the use of discrete-time integral SMC, for which analogous results in continuous time are reported in [19], [20]. Applications of these combined schemes to nano-positioning systems, to microgrids, and to three-phase AC/DC converters, are reported in [21]- [23], respectively.…”

This paper proposes a discrete-time sliding mode control (DSMC) strategy for linear (possibly multi-input) systems with additive bounded disturbances, which guarantees the satisfaction of input and state constraints. The control law is generated by solving a finite-horizon optimal control problem at each sampling instant, aimed at obtaining a control variable that is as close as possible to a reference DSMC law, but at the same time enforces constraint satisfaction for all admissible disturbance values. Contrary to previously-proposed control approaches merging DSMC and model predictive control, our proposal guarantees the satisfaction of all standard properties of DSMC, and in particular the finite-time convergence of the state into a pseudo sliding mode band.

“…When the system is in sliding regime, the converter dynamics is forced to evolve over the sliding surface, and the new dynamics can be derived according to the invariance conditions.σ (k + 1) = σ (k ) = 0 Then, taking into account the aforementioned expression, the discrete equivalent control can be found by using (5) and (14) in (16). Then, the expression of the control law is obtained as:…”

A three‐phase three‐level VIENNA rectifier has been widely used in the data center DC power supply and AC/DC hybrid power supply system with the advantages of without dead‐time, low switch voltage stress and small grid‐current harmonic. However, the performance of grid current strongly depends on the controller parameter, and the unreasonable controller parameter may deteriorate the grid current. To effectively improve the static and dynamic performance of grid current, a new kind of carrier‐based pulse width modulation scheme based on the double closed‐loop discrete sliding mode strategy is put forward. Further, a modified exponential reaching law is presented to effectively improve the shaking shock effect caused by the traditional sliding mode surface and the neutral voltage dc wave suppression strategy is then presented. To verify the correctness and effectiveness of the proposed sliding mode control strategy, a complete simulation model and experimental prototype platform under the digital control is established, the detailed theoretical analysis and design method of the proposed control strategy are presented. The simulation and experimental results show that the steady and the transient performance of the grid current with the proposed control strategy are effectively improved, and the neutral voltage in dc side is kept balanced at the same time. © 2020 Institute of Electrical Engineers of Japan.

“…In the SMC, a control law is designed to keep the control variables on the sliding surface. 5,[30][31][32][33] Due to the fact that the switching is discontinuous and the high switching frequency is not infinite, the undesirable chattering phenomenon characterized with oscillation having finite amplitude and frequency is observed in the SMC. The chattering problem affects the control accuracy and increases the power loss, which hinders the practical application of SMC.…”

Summary In three‐phase pulse width modulation rectifiers, proportional integral (PI) has been used in voltage outer‐loop to obtain the active current reference when using the conventional model predictive control strategy. However, the performance of the dynamic response is poor as large step and longer settling time are required on the active power under the load variation. To cope with this problem, a sliding‐mode controller can be employed to replace the PI controller. Nevertheless, the sliding‐mode variable structure control is discontinuous which leads to the chattering problem. In this work, a novel control strategy which combines a simplified model predictive control and a modified sliding‐mode control is proposed and investigated. The proposed strategy is supposed to reduce the effect of unexpected disturbances such as the DC‐link voltage step and the load variation. Simulation and experiments have been conducted for validation. The results indicate that the proposed strategy is feasible and has excellent dynamic response. Furthermore, it is easy to design and implement.
