Torsional drivetrain vibrations in hybrid and electric drivetrains, which occur during traction and braking control, are commonly encountered. This problem occurs mainly due to the weak damping characteristic of the hybrid/electric drivetrain and the fast time response characteristics of the electric motor. An active motor damping (AMD) control algorithm for a hybrid electric vehicle, considering ABS braking maneuvers on different road conditions, is developed in this work. The control problem is structured such that the control objective is disturbance rejection against the estimated brake torque signal received from the ABS module. Communication delay between the ABS and motor control module is handled within the control strategy. State feedback control strategy is used with the linearized version of the non-linear state-space equations together with an Extended Kalman filter. Gear backlash is taken into account without the need to estimate the mode of backlash. In the development of the controller, state feedback gains are set such that the ABS functionality on tire slip regulation is not altered. Existing studies in the literature feedback only the angle of twist and axle wrap angular speed for damping the vibrations. The structure of the controller in this study is different in that it estimates and feeds back tire slip, in addition to these two. Simulation results show the effectiveness of the controller in reducing the angle of twist without deteriorating ABS tire slip control and braking performance of the vehicle.

Optimum geometry for torque ripple minimization of switched reluctance motors Sahin, F; Ertan, Hulusi Bülent; Leblebicioğlu, Mehmet Kemal (2000-03-01) For switched reluctance motors, one of the major problems is torque ripple which causes increased undesirable acoustic noise and possibly speed ripple. This paper describes an approach to determine optimum magnetic circuit parameters to minimize low speed torque ripple for such motors. The prediction of torque ripple is based on a set of normalized permeance and force data obtained from numerical field solution for doubly-salient geometries. For that purpose a neural net is trained to extract the data neede...
Vibration reduction of structures by using nonlinear tuned vibration absorbers Doğan, Muhammed Emin; Ciğeroğlu, Ender; Department of Mechanical Engineering (2019) Tuned Vibration Absorbers (TVA) are commonly used in reducing undesirable vibrations of mechanical structures. However, TVAs work in a very limited frequency range and if the excitation frequency is outside of this range, they become ineffective. In order to solve this problem, researchers started to consider nonlinear TVAs for vibration attenuation. In this study, dynamic behavior of a Linear systems coupled with a nonlinear TVA is investigated. The system is subjected to sinusoidal base excitation. Parame...
NONLINEAR DYNAMIC-MODEL AND ITS SOLUTION FOR A HIGH-SPEED CAM MECHANISM WITH COULOMB-FRICTION Ünlüsoy, Yavuz Samim; Tümer, Sami Turgut (Elsevier BV, 1994-01-20) The dynamic behavior of overhead cam mechanisms, commonly used in automotive applications, is strongly influenced by the Coulomb friction at the rocker arm pivot. In this study, a non-linear one-degree-of-freedom model of such a mechanism including Coulomb friction has been developed. An exact quasi-linear solution to the equations representing the non-linear behavior has been obtained. The effects of Coulomb friction at different cam speeds are investigated using typical parameter values. A critical examin...
Active vibration control of a smart sandwich plate via piezoelectric sensors and actuators Aksoy, Yunus Tansu; Şahin, Melin; Department of Aerospace Engineering (2015) In this study, the first three vibration modes of a smart sandwich plate, which are 1st out-of-plane bending, 1st torsion and 2nd out-of-plane bending modes, are aimed to be suppressed by using active vibration control techniques comprising a pole placement controller. Smart sandwich plate is composed of a passive sandwich composite plate and piezoelectric patches (PZT Lead-Zirconate-Titanate) attached with epoxy adhesive at specific locations determined by using finite element modelling and analysis. Those...
Adaptive ride comfort and attitude control of vehicles equipped with active hydro-pneumatic suspension Saglam, Ferhat; Ünlüsoy, Yavuz Samim (2016-01-01) In this study, an active suspension for combined ride comfort and attitude control of a vehicle equipped with hydro-pneumatic (HP) suspension system is developed. The state-dependent Riccati equation (SDRE) control is employed in the design of the active suspension controller. A detailed sensitivity analysis is performed to examine the effects of the selection of weighting coefficients on the ride comfort and attitude control. According to the results of the sensitivity study, three different sets of fixed ...
