The purpose of the paper is to propose a new control scheme in active front steering (AFS) for vehicle stability using disturbance observer method. In the paper, the ideal yaw rate can be calculated on the linear two-degrees-of-freedom vehicle model. In addition, the actual sideslip angle can also be estimated by using a state observer. Based on this, two kinds of baseline AFS controllers are proposed...
The active front steering (AFS) technique is one of the effective methods to handle the stability of a vehicle. In this paper, some AFS control schemes have been proposed. First, a two degree of freedom mathematical model for the vehicle dynamics has been introduced in order to calculate the desired yaw rate. On this basis, the actual sideslip angle is further identified and estimated by constructing...
Testing of mixed-signal SoCs becomes one of the pressing challenges due to enormous test cost including ATE expenses, design for test (DFT) hardware overhead and test application time. Prior researches focus mainly on minimizing test cost for digital SoCs under the constraint of ATE test resources and power consumption. A self-hold analog test wrapper design and pipelined parallel test manner are...
Armed at solving the problems appeared in researching servo control system of bomb-disposed robot at a distance, adopting Zhangpsilas image calibrating method, accomplished the both eyes stereo-identity mission. Having found the geometry solution for every manipulator joint angle, avoided finding the solution of inverse process of the kinematics. Have applied the RTW code to generate a software ,...
