The Application of Optimal Control of Active Suspension Based on Precise Integral Method
Riding comfortably and handling safely of vehicles has been influenced directly by the dynamic performance of suspension system. As the parameter of conventional passive suspension system been fixed, the external energy has been absorbed and stored passively. With the surround traffic conditions and outside inputs changing, the passive suspension system can’t take initiative to adapt [...]
Study on the Control of Longitudinal Platoon Based on the Communication Network
The throughput of vehicles on highways can be greatly increased by forming vehicle platoons.The control law that maintains stable operation of a platoon is dependent on the lead vehicle’s velocity and acceleration transmitted by wireless communication network.Communication networks generally introduce packet dropout and delay.However,these communication faults are not typically taken into account in controller designing.Therefore,this [...]
Robust Synchronization Control of Dual Cylinder Hydraulic Drive Systems
With the urgent need for high-precision synchronous technology of hydraulic drive systems of the metal processing equipment, metallurgical machinery, engineering machinery and aerospace devices,it becomes increasingly important to investigate the synchronization control theory and method for the electro- hydraulic servo drive systems. To this end, the synchronous control problem is discussed in this paper for [...]
The Stability and Control of Vehicle Following System
The stability of the systems is an important factor in the theory of dynamic systems, it make the controlled object meet the design index exactly. And the property of stability determines whether the disturbed-system can return to the original balance state. In practical control system, due to the limitation of information processing and signal transmission [...]
Vibration Control Technology of Active Vehicle Suspensions
With the development of automotive technology, active vehicle suspensions system is increasingly becoming research focus. The current study about vibration control technology of active vehicle suspensions still remained at the theoretical stage. There are several issues needed to be resolved. First and foremost, a good system model must be needed for the vehicles are complex [...]
UVA Cooperative Searching with and Without Adversaries
UVA cooperative searching is an important research area in cooperative control. An approach of distributed algorithm is presented to solve the time delay problem and a framework of path planning in adversarial environments is studied.MDMPC is an approach based on Decentralized Model Predictive Control theory. By using this method the searching problem is decoupled completely. [...]
Nonlinear Dynamics and Delayed Feedback Control of Micro-gyroscope System
In this thesis, the nonlinear dynamics behaviors and theirs delayed feedback control of a micro-gyroscope system are investigated, and the following results are given. Firstly, the differential equations of motion of the micro-gyroscope system are obtained based on the Lagrange equation, and then simplified with the actual working condition. For the free vibration of the [...]
Research and Implement of Automatic Detection Algorithm and Software Implement for the Thickness of Highway Pavement Based on GPR
As China’s growing highway mileage, the traffic is rising, and the number of overweight vehicles is increasing, coupled with the unreasonable construction of highway, the majority of highway appears early disease. So we need efficient freeway disease detection equipments. Ground Penetrating Radar (GPR) is a new and non-destructive testing equipment, it is widely used in [...]
Research of the Multiplexing Technology Based on Advanced Orbiting System
With the growing complexity of space missions and the growing completion of space facilities,the demands of the data processing have become more higher to the space’s data communication system.In 1986 CCSDS developed Advanced Orbiting System(AOS) based on the Conventional Orbiting System(COS) in order to meet the complexity and high data rate of the transmitted information [...]
Technologies on Control of Time-delay Behavior for Active Heave Compensation
Active heave compensation system(AHCS) is an important equipment of offshore sealift which compensate the relative motion between supplying and supplied ships caused by ocean wind, wave and flow, ensuring the sealift safely and smoothly. However in practice, the big inertia of the crane and the load, and the effects of components characteristics in both hydraulic [...]
