Paper deals with industrial realization of feedback control of demanding applications on their control, control algorithms and visualization together with design, implementation and real time control from MATLAB/Simulink Environment. Paper shows direct connection and implementation way of designed control schemas of prepared applications to an industrial WinPLC. Described is a way to produce a permanent solution in control applications that are fully prepared, designed and implemented directly from MATLAB/Simulink to the target control platform. As a part, the mentioned solution is using a multiplatform control system REX as a bridge between MATLAB and target platforms. These methods allow minimizing costs of development of control of applications, because it produces target permanent realizations in comparison to classical development methods that usually need expensive real time measurement cards and produce only one purpose development solution.

The behavior of a vehicle is strongly influenced by the distribution of driving and braking torques in four wheels. Therefore, traction and stability characteristics of a vehicle can be controlled by the controlling driveline and the braking torques. However, independent and uncoordinated control of the brake and driveline control system can harm the vehicle performance due to the interference between two devices. So, the vehicle equipped with both the brake control system and the driveline control system requires a coordinated control of both systems to reduce the bad interference and to maximize vehicle performance. This paper presents the procedure of the coordinated control design of the brake and driveline control systems. The 2 degree of freedom (DOF) vehicle model and the driveline model including torque biasing devices are developed. Each control algorithm for the ESP and the coupling (the target torque biasing device) are developed based on the models. Finally, the coordinated control is designed to maximize the yaw stability of the vehicle. The developed models and the control algorithms are programmed using Matlab/Simulink and verified by co-simulation with a commercial vehicle simulation tool, CarSim.

The aqua-plasma, non-thermal plasmas in liquids, can be discharged by forming the vapor coverage by Joule heating on the metal electrode. The electric field is decided by thickness of vapor coverage with applied voltage. It implies that the thickness of vapor coverage is the key parameter to the control the characteristics of aqua-plasma. The aquaplasma electrode consists with discharge tip, dielectric, and counter electrode. The tip covering vapor attaches on the dielectric with high surface tension coefficient. In this work, the effects of dielectric temperature on the mode transition of aqua-plasma are studied. The aqua-plasmas are discharged by applying ac driven voltage on the saline immersed discharge tip, size of 400 μm. The temperature of dielectric is controlled in range of 330 K - 500 K by varying the thickness from 90 μm to 780 μm. Ground electrode is placed under 30 mm of the tip. The V-I signals are monitored by using the voltage and current probes. The aqua-plasma shows three different modes with the thickness of dielectric; Townsend mode, glow-like mode, and spark mode. In case of 0.09 mm, dielectric temperature is relatively low, 330 K, due to thermal conduction from heated electrode to electrolyte. The spark discharge simultaneously occurs with the formation of vapor, 150 μm, with electric field of 5.2 MV/m. The vapor coverage is collapsed by high dose of plasma charge and re-built. In the 0.78 mm, dielectric temperature reaches to 500 K by low thermal conduction. Thickness of vapor coverage increases to 220 μm. The electric field is reduced to 3.4 MV/m and vapor coverage is maintained, Townsend mode streamer discharge takes place. The vapor coverage is oscillating since streamer heats up the vapor surface. In the intermediate dielectric thickness, 0.35 mm, glow-like discharge occurs. Also the rotation temperatures of aquaplasma produced ·OH* (T rot_·OH* ) are estimated by using the Boltzmann plot method on the OES. The two different T rot_·OH* are

This paper presents an application of linear-Parameter-Varying (LPV) control to solve the torque vectoring problem of a through-the-road hybrid electric vehicle (TtR-HEV). To achieve high performance both in reference tracking and disturbance rejection, a two-degree-of-freedom LPV self-scheduled controller is synthesized by using mixed sensitivity loop shaping. The controller is based on a single Lyapunov function and guarantees stability and a level of control performance for all admissible trajectories of varying parameters. Moreover, an anti-windup control scheme is derived by employing a two-step design procedure. Finally the designed controller is tested in various driving maneuvers and compared with a flatness-based controller.

Factory waste includes the incomplete combustion of industrial fuels that causes carbon to precipitate in vents. These carbons might be put to good use. Therefore, the impact of using waste carbon in factories to produce electricity is investigated in this study by evaluating electrical characteristics: the type of electrode material's suitability, the size of the electrode's carbon contact surface area, and the distance between the electrodes. According to the findings, the maximum open circuit voltage (V oc ) was 1.09 V for copper (+) and zinc (-) electrode materials, 1.11 V for the electrode's carbon contact surface area, and 1.29 V for the electrodes' spacing. The maximum of V oc was 1.11 V, maximum on-load voltage and current were 0.64V, 124.65 mA for optimum electrode carbon contact surface size 40 cm 2 . Optimum electrode distance at 2 cm that maximum open circuit voltage (V oc ) was 1.29 V. The maximum load voltage and current were 0.77V, 128.32mA. Factory waste carbon can be useful in some applications for producing electricity from waste carbon and assisting in the reduction of factory waste.

This paper presents the development of control technique for an internal combustion engine which controls fuel injections for various gasoline/ethanol mixtures. Yamaha motorcycle, Spark 135i, is tested to find the injection timing for E0, E20, E85 and E100, respectivelty. The experiments are conducted with a speed up to 8000 rpm and working load between 0-95 percents of the full span in Engine Dynamometer. A signal from an oxygen sensor installed at the exhaust pipe are sent to the fuel injection system and served as a feedback signal, in order to maintain a complete combustion during a testing period. The result shows that the injection timing for E20, E85 and E100 are longer than the one for E0 8.0 percents, 34.2 percents and 44.8 percents. The approximate injection timing at different ethanol ratio can be determined by using these experiments with the error of -6.8 7.3 percents. In addition, The results can be used to develop an injection control system for flexible fuel.

There have been a number of methods proposed for accurate state of charge (SOC) estimation of a battery as an important role of the battery management system (BMS). However, adequate test data of batteries and BMS development costs must be taken into consideration before application in actual vehicles. In addition, different algorithms need to be adopted according to the type of energy storage device and system configuration. For a mild-HEV hybrid energy storage device that uses the ultracapacitor module and the VRLA battery, the small capacitance of ultracapacitor module makes accurate SOC difficult. Accordingly, this paper introduces a dynamic SOC estimation algorithm capable of SOC compensation of the ultracapacitor module even when there is current input and output. A cycle profile that simulates the operating conditions of a mild-HEV was applied to a vehicle simulator to verify the effectiveness of the proposed algorithm based on testing.

In this paper, a fuzzy force control algorithm is suggested for commercialized industrial robots equipped with the position servo drives, where control rules of the proposed fuzzy controller are changed according to the magnitude of environmental stiffness in such a way that good force response is maintained regardless of changes of environmental stiffness. Specifically, some fuzzy control rules are designed for several representative environmental stiffness values, and then a control action for a given arbitrary environmental stiffness value is decided by a fuzzy interpolation method. To show the validity of the proposed fuzzy controller, several experimental results are illustrated, where a 5-axis articulated robot manipulator equipped with the wrist force/torque sensor system and our prototype dual robot controller are employed.< >

Study on the reduction of inherent noise in magnetic field has been conducted. Distributed model such as magnetic field is well known for its inadequacy to control in conventional ways. 'Stochastic system identification method' from moment equations via Fokker-Plank-Kolmogorov equation has been developed in inverse manner to figure out unknown system parameters of discrete system under random disturbances. The newly developed concept of 'stochastic system identification method' is implemented on magnetic system, which enables to construct virtual discrete operating system in forms of 2 nd order using stationary stochastic system output only. Based on the virtually assumed dicsrete model, system parameters are extracted. In order to reduce the noise, ' Hoe-stochastic controller' is designed for the virtually generated discrete model of magnetic field. Also in order to perform system control in real time frame, approximate probability density function is adopted to design the 'Heo-stochastic controller' and implemented on the system. Feasibility of the idea to control stochastic distributed system via 'stochastic system identification method' and 'Heo-stochastic controller' is confirmed in terms of simulation and experiment as well.
