A servo controller for redundant force is designed based on DOF shaking table. Firstly, according to the geometric position of hydraulic cylinders, the composition and decomposition matrix are achieved. Secondly, in order to reduce the coupling on shaking table, which derives from redundant force within the system, force transformation matrix is calculated. Thirdly, a three-variable controller is...
This paper concerns with the dynamics of TH equations both in the time domain and in the true anomaly domain. Based on the homogeneous solutions of TH equations, a state transition matrix for the TH equations in the true anomaly domain is obtained. The state transition matrix applies to any eccentric orbit. Through the state transition matrix, the sampleddata descriptions are obtained for both the...
On the basis of the establishment of articulated truck model and hydraulic steering system model, this paper establishes optimal direct yaw moment control strategy based on the main and auxiliary control variables. The main control variables are side slip angle and yaw rate of vehicle, and the auxiliary control variable is the articulated angular acceleration. The handling and stability of articulated...
Wheel skidding or spinning is dangerous for driving vehicles, and compared to conventional vehicles, electric vehicles are more easily to slip during driving on slippery road. In this paper, a novel traction control method based on wheel-slip control is proposed to improve the safety and stability of electric vehicles. Considering the high nonlinearity and uncertainties of the traction system, this...
According to the high requirement in environment of tracking for humanoid robot based on vision, a recognition algorithm and control method is present using depth information extraction. The depth information is gathered by a Kinect camera from Microsoft, and an accelerated algorithm is proposed to improve the real-time requirements of image recognition. The obstacles information and robot status...
Guidance is critical for a probe to land on the moon surface successfully. This paper mostly discusses about the guidance law in deceleration process of lunar soft landing. Based on some hypothesis, it creates the dynamics model which is built in the coordinate system of soft landing. Then the suboptimal fuel-consuming guidance law is designed for the purpose of reducing fuel consumption. Output errors...
This After the alignment of the missile's inertial platform system, the inertial platform will be maintained in the inertial frame, this make the inspect of the platform misalignment hard to be achieved by using conventional algorithm. In this paper, an approach of misalignment self-inspect for missile's inertial platform is described. By using the in-motion alignment technique of strap-down inertial...
This paper presents and evaluates a differential geometric model for single and double track vehicles, which allows to estimate internal state parameters (steering angles, velocities, wheel speeds, …) from a given planar trajectory over time. Possible applications include accident reconstruction from video footage, constraining trajectory optimization by physical limits, and extracting control parameters...
