“…Compared with the above-mentioned disturbance compensation methods, a method, which does not need the inverse model of the system (this effectively avoids the cancelation between unstable poles and zeros) and does not require external disturbance information or accurate system model, has greater advantages. She et al 31 proposed such the method of equivalent-input-disturbance (EID). The method uses a state observer and an estimator to estimate the signal on the control input channel, which has the same impact on the system output as external disturbance has, to realize the active compensation for the disturbance.…”

The speed control performance of permanent magnet synchronous motor (PMSM) drive system is degraded due to non-matching disturbances such as parameter perturbation and load torque mutation. This paper presents a nonlinear generalized predictive control method based on equivalent-input-disturbance (GPC-based-EID) to realize the fast response and strong robustness of the speed controller of the PMSM drive system. Firstly, the continuous time nonlinear system of a motor mechanical equation is established. A speed controller based on the generalized predictive theory rather than the PI controller of a traditional vector control is designed. Then, the drive system with disturbance is transformed into an EID system. An improved nonsingular fast terminal sliding-mode observer (NFTSMO) is introduced to accurately estimate the EID of total system non-matching disturbances. And the active compensation of non-matching disturbances is realized through feedforward method. This greatly enhances the robustness and the speed tracking performance of the drive system. Comparisons with PI control, traditional GPC and GPC-based-ESO methods show the effectiveness of the method.

“…This changes the structure of an original controller and greatly increases the risk of system instability. She et al (2014) introduced an equivalent-input-disturbance (EID) theory to solve this problem for system disturbance. The EID method is effective in rejecting disturbances from control input channels and does not need to know the inverse model of a system (Cai et al, 2019;Wu et al, 2020).…”

The reliability of permanent magnet synchronous motor (PMSM) systems is very important in high-precision industrial drives. However, disturbance or sensor fault may cause the performance degradation of the system. This paper presents an improved sliding-mode-observer (SMO)-based equivalent-input-disturbance (EID) approach for the rejection of faults in current measurement circuits of a PMSM drive. A system model, which contains faults in current measurement circuits, is first constructed by using EIDs in control input circuits. Then, an improved SMO is designed to estimate the equivalent-input-faults. The effect of the faults on the system is rejected based on the EID theory. Moreover, the global stability and convergence analysis is also provided. Experiments and comparisons demonstrate the effectiveness of the method.
