“…Finally, experimental measurements of the device displacement, velocity, and shear force were used to validate the performance of the proposed model and the IFFOA. Shao et al [56] combined chaos search and a Gaussian mutation operator into a traditional artificial fish swarm algorithm and proposed an improved artificial fish swarm algorithm (IAFSA) method. The effectiveness of the IAFSA was verified through steady-state response and dynamic friction experiments.…”

In a high-precision servo system, the nonlinear friction link is the key factor affecting the system performance. Reasonable solving of the friction link in servo systems has become a focus of current research. This paper summarizes the friction nonlinearity that affects the control performance of servo systems. First, the characteristics of friction are summarized, and the advantages and disadvantages of typical friction models in recent years are analyzed. Subsequently, existing friction model parameter identification methods are introduced and evaluated. On this basis, the development level of the friction nonlinear control strategy is analyzed from three aspects: friction model-based control, friction model-free control, and compound control. Finally, the objective advantages and disadvantages of the existing technology are summarized, and the future development direction of the friction model and selection reference for the nonlinear friction control strategy are comprehensively discussed.

“…However, since the Coulomb’s hypothesis, a significant amount of effort has been made to establish an accurate friction model. Among them, the LuGre friction model proposed by Canudas de Wit 27 can describe both the dynamic friction and static friction with high accuracy and has been widely used in servo system and motion control; 28–30 therefore, it is suitable for the conditions used in this paper. Hence, the LuGre friction model is employed to describe the friction between the mover and supporting parts of the actuator.…”

To acquire a perfect vibration isolating performance in the active controlled mount system, a precise model for the actuator is required. In this study, we introduce a novel nonlinear lumped parameter model of the electromagnetic actuator for the engine’s idling or low-speed condition. The model considers not only the nonlinear characteristics caused by the reluctant force, cogging force, and magnetic saturation but also the friction between the mover and the supporting parts. The LuGre friction model is employed to describe the friction during the mover’s reciprocating motion. Then, the quasi-static actuator force of the electromagnetic actuator under constant currents is measured to identify the nonlinear parameters of the model, so is the nonstationary actuator force measured to identify the parameters of the LuGre friction model. Finally, a specific experimental scheme is proposed for validation, in which a suspended ring-shaped iron is added as the actuator’s load. This configuration limits the displacement of the mover effectively, allowing the actuator operate at a frequency of 20–50 Hz and at a peak actuator force of about 8 N, which is close to the actual working condition of the active controlled mount in the engine’s idling or low-speed condition. The results show that the proposed lumped parameter model is able to predict the dynamic characteristics of the actuator precisely. The root mean square errors of the current and actuator force are relatively 3% and 10%, respectively.

“…The recursive equations of the LuGre model were solved, and the problem of effectively detecting mane microdisplacement was discussed by Guo et al [12]. Shao proposed a new modified LuGre model suited to a high-speed mechanical system with friction as well as an improved artificial fish swarm algorithm (IAFSA) method that introduced the chaotic search and Gauss mutation operators into a traditional artificial fish swarm algorithm in order to identify the parameters in the proposed modified LuGre friction model [13]. The angular speed over the zero phenomenon occurring in the angular speed free reduction was used to acquire the microdisplacement of the mane in reference [14].…”

The load characteristics for the flow regulator of a solid ducted rocket are discussed in this paper. The mechanism and the influence factor of the load in the flow regulator were studied both theoretically and experimentally, and the system load and the working load were divided according to the mechanism. Additionally, the load influence on the working quality of the flow regulator and the ducted rocket were analyzed. System modeling of the flow regulator was carried out based on the working mechanism of the gas generator and the Stribeck friction model, and models of the actuator, gas generator, and load were built. Furthermore, considering the identification of the model parameters and the inapplicability of the conventional Stribeck identification method to the flow regulator, a new Stribeck model parameter identification method was proposed. A sine wave was used as the signal source, and specially designed devices were used to accomplish the switch of the working condition. Through the use of the genetic algorithm, the rotational inertia and parameters of the system load and working load were identified by stages. Finally, the validation of the identification method was carried out with a simulation.
