The characteristic of the MSM over the conventional sliding manifold is capable of ensuring the sliding mode proceeds from an arbitrary initial state and thus achieves the robustness against system uncertainties. The inverter tracking performances of steady-state and transient responses can be improved due to speedup-reaching the sliding manifold. A 60 Hz 400 W prototype is built with MSM control scheme based on dSPACE DSP by sensing the output voltage for the closed-loop feedback. The experimental results show that low total harmonic distortion (THD) output voltages under resistive load or even under rectifier-RC load and fast transient response subject to step change in load are obtained. Design procedures, computer simulations, and experimental results are provided to demonstrate the performance of the MSM controlled inverter.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128650905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the research is controlling the landing posture without structural damage. First, the equations governing the dynamics of the twin-body system are established based on the Lagrange-Euler formulation. The damping uncertainty caused by the actuators with bearing would be considered, and the robust controller is designed based on the sliding control and applied to achieve the control object.

The limited stroke length of the linear motor driving the PDIP and the varying friction distributed on the linear motor track posed a challenge for control design. Therefore, a cascade control structure is considered in this study where the inner loop is formed via state feedback and MPC directs the outer loop to enhance position control of the linear motor. Swing-up control of the PDIP was achieved with energy-based control techniques. Experimental results demonstrated successful swing-up and balancing of the two pendulums in their up-right positions. Compared to the conventional state feedback control, the cascade control structure improved the performance of the position control in the PDIP without the need for a precise friction model.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132590653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in the present study, we have developed a method that enables the searching of similar images at high speeds and with high accuracy and the search involves uniform processing time, even in the case where a large-scale database is used. This is achieved by clustering databases having approximately uniform amounts of data using self-organization, including self- multiplication and self-extinction, and by collating the input images with the data in the database by means of the low-order image characteristics, while narrowing the search space in accordance with the past history. By estimating the sequential images of the finger shape by using this method, we successfully realized a process involving a joint angle estimation error within several degrees, a processing time of 150 - 160 fps, and an operating time without dispersion by using a PC having a CPU clock frequency of 2.8 GHz and a memory capacity of 512 MB.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130408363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integration technique is particularly emphasized, where the output of the motor should match the characteristic of the propeller. Also, for such a hubless rim-driven construction, the motor is embraced within the duct, and the motor size will consequently determine the duct thickness. Therefore, the drag force due to the duct should be analyzed and calculated as a design consideration for the propeller and motor. The specifications of the thruster are determined based on the thrust requirement of the target ROV. Several types of software are used for analyses of hydrodynamics, motor magnetic field, etc, and the design information is exchanged around.

The vibrator driven by four piezoelectric actuators is newly developed in which a special vibration mode of the actuator can be excited by two perpendicular electrodes, placed on a 5times5times5 mm3 piezoelectric ceramic block. Compared with conventional piezoelectric actuators, the actuators implemented in the ALG have several advantages such as a simple structure, easy assembly, single phase driving and accessibility to change the movement's direction. Due to these features, structure miniaturization can be attained. The vibration behavior of the actuator is investigated by the finite element analysis. The simulation results are compared with the measurement on the surface of the actuator. In this paper, we successfully integrate the actuators and the miniature linear guide into the ALG.

The LC Alter design is constrained by the total harmonic distortions of the stator voltage and inverter output current, the voltage drop in the filter inductor, and the system resonance frequency. The last constraint is important from the control point of view, because the vector control requires that the sampling frequency is sufficiently higher than the resonance frequency. The design takes into account the frequency dependence of the filter resistance and inductance due to the eddy currents in the laminated iron- core inductor. The design method is further enhanced by taking into account the inverter power stage cost as a function of the switching frequency. The design minimizes the total cost of the inverter and filter, and determines the optimal switching frequency. Simulations and experiments show that the filter designed according to the proposed design procedure fulfils the design constraints, and the speed-sensorless control works well with the cost-optimized filter.","PeriodicalId":199609,"journal":{"name":"IECON 2007 - 33rd Annual Conference of the IEEE Industrial Electronics Society","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127008340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
