“…These applications include but are not limited to the fields of spontaneous synchronization of generators in power grids [12], protein structure dynamics [32], and vibration control [33,34]. Next, we will consider the impact of external drivers [35,36]. How the parameter configuration affects the system with damped forced vibrations is still an open question.…”

Heterogeneous oscillator networks consist of a dynamical function that describes the state of the oscillator (containing several parameters) and a topology that reflects the connections between the oscillators. Revealing the macroscopic dynamics of systems under different configurations of parameters and topology is a topic worthy of discussion and comes with great challenges. In this study, we discuss the effect of different parameter configurations on the damped free vibration of a classical spring oscillator network. On the regular network, we give the analytical expression satisfied by the free vibration of the system under over-damping and critical damping. Furthermore, we discuss the fastest and slowest exponential rates of decay of the system for different parameter conditions. In conjunction with quadratic eigenvalue theory, we extend the above analysis from regular networks to complex networks. We give a general method for calculating the eigenvalue spectrum of the system for arbitrary parameter configurations. In conjunction with the stability of the system and the rate of decay of the exponential rate, we also give numerical simulation results for the second largest and smallest real parts of the eigenvalues of the system. Finally, through the comparative analysis of the simulation results, we relax the matching relationship between the three parameters (mass, damping, and degree) to the matching between two parameters (mass and damping). topics: parameter configurations, damped free vibration, over-damping, critical damping

“…Further, an adaptive active control scheme has been developed by combining model prediction and Butterworth filter control to solve the torsional vibration problem. 8 In addition, the filtered-x least mean square algorithm 9 and a model reference controller have been implemented. 10 Moreover, a previous work has improved vehicle drivability by using a linear quadratic tracking controller with a model reference adaptive technique.…”

To address vehicle drivetrain vibrations that cause discomfort and poor drivability, this study proposes a new active damping strategy with simple backlash compensation based on the simultaneous perturbation stochastic approximation (SPSA) with norm-limited update vector. First, an experimental device developed for a simplified drivetrain mechanism is demonstrated. A mechanism for reproducing both the contact mode and the backlash mode is included in the device. For the contact mode, a model-based [Formula: see text] controller is employed as the baseline damping strategy. Further, to mitigate the backlash effect, a simple algorithm based on mode-switching-based compensation is used with the [Formula: see text] controller. In particular, for the critical controller parameters, this article presents a systematic design approach to search for their optimal values. The key parameters, which are needed for the backlash and contact mode controllers, are simultaneously auto-tuned using norm-limited update vector-based SPSA, which ensures the stability in the iterative tuning. The novelty of this study is that both the backlash mode controller and the contact mode controller are simultaneously optimized by the improved version of SPSA, thus realizing a comprehensive auto-tuning design of an active drivetrain damping system. Finally, the active controller is experimentally verified using the actual test device. Comparative studies show that the proposed approach significantly reduces drivetrain vibrations and is robust against fluctuations in the backlash.

“…Active vibration suppression has been known to be one of the powerful countermeasures because it allows for higher attenuation effects based on advanced control technologies. For example, a disturbance rejection approach with an adaptive disturbance observer (ADO) [11], an adaptive active control [12], and a model reference adaptive linear quadratic tracking (ALQT) controller have been implemented to effectively reduce vehicle oscillations [13]. Recently, the development of controllers with network communication-induced delay compensation has facilitated implementation in modern vehicles [14], [15].…”

For enhancement of the drivability and lifetime of the components, reduction in vehicle driveline oscillations has been addressed by advanced active control algorithms. However, most of the existing works involve subjective determination of their critical controller parameters, imposing heavy adjustment tasks on designers. This research presents an efficient tuning algorithm of the model-based driveline vibration controller that explicitly considers the adverse influences due to nonlinear backlash. First, a driveline dynamics model with a dead-zone effect of backlash is established. A dynamic output feedback 𝐻 2 controller is designed as a baseline controller to attenuate the low-frequency resonance of a driveline. A simple control mode switching algorithm is combined with the controller to deal with the backlash nonlinearity. The optimal values of their important design parameters included in the active control system are automatically searched by a computationally efficient algorithm, i.e., the simultaneous perturbation stochastic approximation (SPSA). The proposed active oscillation controller tuned by the SPSA is validated via several simulation tests. The robustness is evaluated for various patterns of driveline dynamics fluctuations such as the model parameters, the length of backlash, and the driving conditions. Moreover, the proposed controller is compared to traditional active controllers including a proportional integral differential (PID) controller tuned by the Ziegler-Nichols method. As a result, the improvement of the vibration suppression performance as well as its robustness originating from the compensation for backlash is revealed.
