Abstract
Permanent magnet synchronous motor (PMSM) with simple structure and high ratio of torque to inertia is used as the energy conversion device to tighten or release spiral power spring (SPS) in spiral spring energy storage (SSES) system. For simultaneous variations of torque and inertia of SPS and nonlinear characteristics of multivariable and strong coupling of PMSM in the operation of SSES system, current incremental backstepping controller is devised through Taylor series expansion based on the built mathematical model of SSES system and designed speed backstepping controller. The stability of the control approach and the robustness of implicit and explicit model parameters are investigated, and the control gains in incremental backstepping control (IBC) are determined. Theoretical analysis indicates that implicit model parameters uncertainty has no effect on the control performance in any case, and explicit model parameters uncertainty hardly affects system performance under IBC with appropriate control gains. The simulation and experimental results show that PMSM in IBC can track the references more accurately and quickly, compared with other three control algorithms. The dynamic tracking performance of speed and current are improved even in an abrupt change of the reference speed, which proves that the proposed control method has strong stability and robustness.
期刊介绍：
Control Engineering Practice strives to meet the needs of industrial practitioners and industrially related academics and researchers. It publishes papers which illustrate the direct application of control theory and its supporting tools in all possible areas of automation. As a result, the journal only contains papers which can be considered to have made significant contributions to the application of advanced control techniques. It is normally expected that practical results should be included, but where simulation only studies are available, it is necessary to demonstrate that the simulation model is representative of a genuine application. Strictly theoretical papers will find a more appropriate home in Control Engineering Practice''s sister publication, Automatica. It is also expected that papers are innovative with respect to the state of the art and are sufficiently detailed for a reader to be able to duplicate the main results of the paper (supplementary material, including datasets, tables, code and any relevant interactive material can be made available and downloaded from the website). The benefits of the presented methods must be made very clear and the new techniques must be compared and contrasted with results obtained using existing methods. Moreover, a thorough analysis of failures that may happen in the design process and implementation can also be part of the paper.
The scope of Control Engineering Practice matches the activities of IFAC.
Papers demonstrating the contribution of automation and control in improving the performance, quality, productivity, sustainability, resource and energy efficiency, and the manageability of systems and processes for the benefit of mankind and are relevant to industrial practitioners are most welcome.
