Actuator Dynamics 액추에이터 역학 - The actuator dynamics are approximated by a first-order plus time-delay dynamic model, and both static and dynamic models of the actuator are identified using a motor test platform. ^[1] Accordingly, a camera mounted OMR is first modeled considering the OMR dynamics, actuator dynamics, and disturbance effects of the target object motion. ^[2] The proposed observer estimates the uncertainty present in the actuator dynamics and the preceding vehicle’s acceleration as the lumped disturbance at the same time, it adjusts the observer gain to alleviate the peaking of control input. ^[3] The actuator dynamics is assessed by means of a functional numerical simulation, involving the mechanical and fluid dynamics. ^[4] The measurement results were used to create the function of the course of the static property of the antagonistic actuator with artificial muscles of the Festo type and to determine a mathematical model of the actuator dynamics, while applying the method of least squares. ^[5] The model considered is a two-axle vehicle with load transfer effects and actuator dynamics. ^[6] Therefore, the OMR dynamics containing the actuator dynamics and dynamic uncertainties are obtained by including the friction present in the OMR and are identified using a system identification method for the actual OMR system. ^[7] The Minimum-Time Slew Optimal Control Problem determines the minimum time, required energy, and optimal trajectory to slew between any two orientations given nonlinear quaternion kinematics, gyrostat and actuator dynamics, and state/input

physical understandings of coupling property. ^[10] This scheme estimates the uncertainty present in the actuator dynamics and the acceleration of preceding vehicle as a lumped disturbance. ^[11] Though it may not be perfect, it is better than totally ignoring the actuator dynamics. ^[12] The performance of LSMC and RSMC solves the uncertainty in the process model which comes from unmodeled dynamics and a simplification of the actuator dynamics, leading to a reduced second order process. ^[13] The error sources, including actuator dynamics, random errors, and nonlinear mechanical backlash, are identified and discussed. ^[14] The proposed control method eliminates the requirement of modeling the CPAs in controller design for each application, and it is based on the online local estimation of the actuator dynamics. ^[15] Conventional l-SMC algorithm from the SMC Aero toolbox is employed for the LV robust, accurate and precise attitude controller design in the presence of the flexible modes, actuator dynamics, and bounded perturbations. ^[16] Driven by actual demands, manipulator and actuator dynamics, state and input constraints, and unknown time-varying delays are taken into account simultaneously. ^[17] A six-state MIMO bicycle model including actuator dynamics of steering and differential braking is used for model prediction. ^[18] Due to the time-critical nature of the control input, in particular its sensitivity with respect to delays/neglected dynamics, the controller is extended to incorporate the effect of actuator dynamics for practical implementation. ^[19] In this paper, taking the actuator dynamics into account, the controller is redesigned by applying the backstepping method to guarantee the asymptotic stability constructing a Lyapunov function, and its effectiveness is shown by numerical simulation. ^[20] In this paper we present a Disturbance Observer Based Control for an octarotor unmanned aerial vehicle, taking into account the actuator

surroundings and actuator dynamics are taken into consideration. ^[22] The influence of the actuator dynamics on the suspension system performance was investigated. ^[23] Meanwhile, actuator dynamics are considered to avoid undesirable performance degradation. ^[24] The proposed algorithm aims at overcoming the most common limitations of the existing algorithms, most of which do not account for actuator dynamics (i. ^[25] Additionally, actuator dynamics and structural modes are identified and used to improve model accuracy. ^[26] In the first approach, the MPC problem is formulated such that actuator dynamics is considered in prediction model. ^[27] To achieve robust finite-time trajectory tracking control, this paper proposes a novel neural-network-based nonsingular fast terminal sliding mode (NFTSM) control strategy for n-link robotic manipulators including actuator dynamics, subject to the model uncertainty and external disturbances. ^[28] This paper deals with the force and motion control problem of holonomic constrained nonholonomic mobile manipulators by including actuator dynamics with the manipulator’s dynamics. ^[29] While dealing with controller design for HCRVs, due to the sluggish nature of a pneumatic brake actuation system, the actuator dynamics has to be considered explicitly. ^[30] Due to the inclusion of the actuator dynamics with the manipulator’s dynamics, the controller exhibits some important characteristics. ^[31] The author described how to account for the effects of turbine nonlinearities and actuator dynamics and saturation. ^[32] ABSTRACT We design reduced-order observers for nonlinear sampled-data strict-feedback systems with actuator dynamics and disturbances. ^[33] Second, a more high-order sliding mode surface is defined for the input of third-order heading tracking subsystem due to actuator dynamics. ^[34] Moreover, unlike the sign-function, a sigmoidal function is realized in the electromechanical systems with actuator dynamics, in which the physical restrictions on the forces and general moments are posed. ^[35] Feedback and actuator dynamics can be directly included in the structural model, leading to accurate models of ac-tuator/structure interaction. ^[36] The control problem is formulated into a three-time-scale singular perturbation formula, including a slow time scale at the rigid robot dynamics, one actual fast time scale at the actuator dynamics, and another virtual fast time scale at the controller dynamics. ^[37] In this paper, controller design for handling constraints on joint position and angular velocity of a single link manipulator with actuator dynamics is presented. ^[38] Inverse dynamics models are used to cancel the differences in actuator dynamics. ^[39] Background, Modelling and
