5. Discussion
- (1)
- Compared with reference [11], the proposed algorithm in this paper has fewer parameters to be tuned, less computational effort, and is more suitable for engineering application;
- (2)
- Compared with [12,14], this paper pays more attention to the robustness of the current regulator when the motor parameters change. First, the robustness of the ADRC current regulator when the motor parameters change during operation is verified through simulation, and through bench experiments, a variety of working conditions are designed for this verification;
- (3)
- (4)
- In order to improve the safety of the algorithm under extreme operating conditions, the anti-windup measures of ADRC are also designed and bench tested under high dynamic conditions, which has not been found in the existing research on ADRC as PMSM current regulator.
- (1)
- Although according to the literature [16], the two gains of LESO can be expressed in the form of observer bandwidth, which reduces the number of parameters to a certain extent. However, compared with PI current regulator, ADRC still has more parameters to be tuned, which limits the application of ADRC to a certain extent. Finding a simpler parameter tuning method is the focus of the next research;
- (2)
- When ADRC is applied to some occasions with high system bandwidth (such as high-speed motors), in order to obtain faster convergence speed and higher observation accuracy, the bandwidth of LESO will inevitably be tuned to a larger value, which will lead to the reduction of noise suppression ability. Therefore, how to reduce the noise impact when the LESO gain is large will be the focus of future research.
6. Conclusions
- (1)
- The performance of LESO is analyzed using the frequency domain method, and the traditional ADRC algorithm is improved in three aspects: observation error compensation, model information utilization and anti windup;
- (2)
- The simulation results show that the improved ADRC current regulator is more robust than the PI current regulator when the parameters change;
- (3)
- The bench test results show that the improved ADRC current regulator has a fast step response without overshoot, good tracking performance and robustness when the load changes and the parameters change. In addition, the anti-windup performance is also verified.
