“…However, because the robust control system generally does not work in the optimal state, the steady-state accuracy of the system is poor. Therefore, robust control is especially suitable for those systems with large variation range of uncertain factors and small stability margin [44]- [46]. In [47], H∞ robust control is used to solve the problem of assembly errors in the center of mass and force of VCM; In [48], robust control is used to reduce the impact of load resonance changes; some scholars also propose to use robust control to solve the problem uncertain external disturbance [49]- [51] and the problem of uncertain system model [52], thereby improving the stability and tracking effect of the system.…”

Voice coil motor (VCM) is a special direct drive linear motor, which can convert electric energy directly into mechanical energy without the use of transmission mechanism. VCM has the advantages of simple structure, good rigidity, fast response, silence, high linearity, no cogging force, no pulsation et al. It is widely used in the field of high-precision control. This paper reviews and summarizes the results of VCM research conducted by scholars from various countries, and summarizes the general situation of VCM servo control technology. Firstly, a basic description of VCM's mathematical model and common control mechanisms is provided. The benefits, drawbacks, and application of control techniques in the field of VCM are all explored in detail; At the same time, the methods to improve control strategy are proposed; Then, combined with the analysis and research of scholars in various countries on VCM, the problems of difficult to establish accurate model, friction disturbance and mechanical vibration of VCM and the solutions to the corresponding problems are summarized; Finally, a summary of VCM's application fields is provided.

“…In the most recent study, the gain of the CNF controller has been designed using the linear matrix inequality (LMI) for time-delay systems [15]. The robust and adaptive CNF controllers have been respectively developed [16,17]. In earlier works [18,19], a combination of the CNF and integral sliding-mode control (SMC) and also the CNF and finite-time robust tracking are, respectively, addressed for synchronization of chaotic systems.…”

The transient response improvement is the most crucial feature of the composite nonlinear feedback (CNF) controllers. This study proposes a novel CNF tuning method for systems subject to saturation. To achieve the goals, the linear part is optimally obtained via a performance index and the linear matrix inequality (LMI). Then, employing the passivity property, a heuristic way is suggested to adjust the nonlinear term. Thus, the automatic and online features would be the key novelties of this algorithm compared with the offline, trial and error, or nonautomatic ones. Some systems are simulated to evaluate the technique and compare with the existing methods. The outcomes confirm that the proposed tuning yields outstanding improvement concerning the aforementioned systems.
