Developing sensors or sensor systems requires precise knowledge of their technical properties. On the one hand the three-dimensional sensitivity of a sensor is of interest. On the other hand the transmission characteristics of transceiver systems, that transfer information or energy, depending on the distance between transmitter and receiver are of particular interest. Measurements can be useful if...
The proposed paper deals with the problem of modelling and simulation of a dual-redundancy Electro-Hydrostatic Actuator (DREHA) by the way of co-simulation based on AMESim and MATLAB. With the development of More Electric Aircraft (MEA) technology, integrated Power-by-Wire (PBW) actuator will be used in the airborne actuation system. As an important PBW actuation system, EHA has virtues of high efficiency,...
A co-simulation on virtual prototype of a type of spot welding robot has been accomplished by combining MATLAB/Simulink with RecurDyn. The control algorithm is executed under MATLAB to generate command forces, which are then exported to RecurDyn environment and applied to actuators of the virtual prototype at each cycle of time. Dynamic control on joint angles was accomplished through the co-simulation...
This paper presents a detailed control system building process for a hardware-in-loop micro-satellite simulator to apply and test system identification or control algorithms. It also designs a new system mechanism to combine the simulator with MATLAB Simulink by DDE, which can enable Simulink to directly control the simulator system and accomplish data sharing and real-time control function. Finally,...
The paper presents the realization of a geometrical model of the RV-2AJ robotic arm built by Mitsubishi using the CAD environment SolidWorks. The geometrical modelling was done according to the robots dimensions and without putting in virtual model the parts that don't have a major influence in his kinematics; like screws, nuts or wires. The robots arm kinematics where then resolved and its schematics...
Networked control system (NCS) is a kind of closed loop control systems where the sensors, the controller and the actuators exchange data through network. Because the networks, in which the band width is limited, are introduced in the systems, some new issues appear unavoidably. At present, the research of networked control system becomes a focus area in control engineering. According to the characteristics...
In this paper, in order to complete multitask underwater, we will propose a kind of novel underwater multi-microrobot system which is consist of a mother submarine and several microrobots with ICPF (ionic conducting polymer film) actuators. Then we simply design the structure and close-loop control system of the microrobot system, study the mission planning and coordinate motion with the formation...

This paper focuses on the problem of robust fault-tolerant control for uncertain linear discrete systems with time-delay. On the basis of Lyapunov theory, it is found that a controller based on a kind of memory feed-back control law can keep the uncertainty systempsilas integrity against the actuator failures, and make use of the LMI toolbox in Matlab, we can get the parameters of the controller....
