Dual-rate dynamic systems consisting of a sensor with relatively slow sampling rate and controller/actuator fast updating widely exist in control systems. The bandwidth these dual-rate is severely restricted by the sensors, resulting various issues like sluggish dynamics closed-loop systems, poor robustness performance. A novel alternating predictive observer (APO) proposed to significantly enh...

This paper proposes a robust dichotomy-based model predictive control (DS-MPC) with fixed switching frequency for the grid-connected inverter (GCI). The proposed fast dichotomy algorithm can select and deduce optimal voltage vector dynamically through space plane. Therefore, DS-MPC strategy could ensure dynamic performance steady-state as well. Also, current robustness be improved disturbance o...

In encoderless Model Predictive Torque Control (MPTC) of three-phase Induction Motor (IM) drives, current sensors can face different electrical or mechanical faults in harsh industrial environments. this research, single-phase sensor Fault-Tolerant (FTC) method for MPTC IM drives without speed measurement using a flux linkage observer and Reference Adaptive System (MRAS) algorithm is proposed. ...
