Chinese control Conference (CCC)

Inspired by the mechanism of fixational eye movement and dynamics of vertebrate's cortex, we propose an active tremor operation (ATO) approach based on dual probes adaptive model (DPAM), and find a resonance phenomena between DPAM and ATO, which is enhanced and suppressed when DPAM and ATO are in-phase and anti-phase, respectively. Based on the observations, we propose a novelty directional selectivity adaptive motion detector. The experimental results show that the motion detector with directional selectivity can detect effectively the edge with specific motion direction, and adapt to the change of illumination and clutter background. The temporal statistic results of motion detection can obviously reflect the motion features of visual object action.

In this contribution we present a new, objective-based controller which works on the basis of a Pareto set, that is the solution of a multiobjective optimization problem. The controller can be used for self-optimizing systems to adapt the system behavior in terms of the desired objectives in spite of unknown disturbances over time. New system configurations are computed, that fit best to the current situation. The objective-based control is realized by means of a discrete controller which operates in a large sample time due to objective evaluation. Parametric reduced models are used to shorten the simulation time during controller design. An active suspension system of a railbound vehicle serves as an application example. The controller is tested with different linear models of the suspension system and is finally applied to a Hardware-in-the-Loop test rig.

Intelligent cane is a robot developed for assisting the elderly or handicapped people in walking. As a nursing-care device, the cane robot is designed to assist the elderly or handicapped people not only in indoor environments but also in outdoor environments. Therefore the cane robot is required to be smaller and lighter. In addition, it is preferred that the cane robot is movable in omni-directions so that it can be used in various situations. A concept called "intentional direction (ITD)" was proposed to estimate the user's walking intention by analyzing signals from a 6-axis force/torque sensor fixed to the handle of the aluminum stick. Admittance control method was applied to the motion control of the cane robot. In this paper, a new algorithm based on the usage and purpose of an ordinary cane is proposed. In the proposed algorithm, the cane robot is appropriately stopped to support the elderly more effectively. The effectiveness of the proposed method is verified through the experiments.

作者： Omid Zebardast Hadi Moradi Farshid Najafi Department of mechatronics engineering University of Tehran Iran Control and Intelligent Processing Center School of Electrical & Computer Engineering University of Tehran Tehran Iran Department of Mechanical Engineering University of Tehran Tehran Iran

In this paper, the design and implementation of a novel passive safe joint is reported. This safe joint is designed for applications, such as an air hockey playing robot playing against a human, in which the force applied by the linkage should be kept below a certain threshold. The proposed mechanism benefits from the compliance of two ramps controlled by the nonlinear behavior of a spring. The passivity of the design, the small footprint, the low cost of production, and the ability to rotate 360 degrees are the main advantages of this design. The mechanism has been designed, evaluated, implemented and tested showing its effectiveness. Finally it has been incorporated in an air hockey robot showing its capability in action.

The activated sludge process is the main versatile technology currently in use for wastewater treatment system. Dissolved oxygen (DO) is the key element in the process due to its significance influence upon the bacteria responsible for decomposing the organic pollutants in the wastewater. However, the non-linear nature of DO couple with the time-varying oxygen transfer rate makes the DO control quite complex. This paper presents an adaptive neuro fuzzy inference system (ANFIS) inverse control of dissolved oxygen in an activated sludge process. The performance of the proposed technique is illustrated with tracking of dissolved oxygen reference trajectory and for comparison PI controller is used. The simulation results revealed the effectiveness and the accuracy of the proposed controller in tracking the DO set point. The controller is valuable for an activated sludge process.

Many systems compete the same finite duration task over and over again, where once each is completed the system resets to the starting location and the next execution begins. Each execution is known as a trial and the duration is the trial length. Iterative learning control algorithms have been developed for such systems where the novel feature is the use of information from previous trials to update the control input for application on the next one. This paper uses the 2D systems structure of iterative learning control to design in one step a control law for trial-to-trial error convergence and along the trial transient dynamics. The analysis makes use of the generalized form of the Kalman-Yakubovich-Popov lemma and the design is evaluated in simulation on a high-speed rack feeder model as a prerequisite for experimental validation. © VDE VERLAG GMBH 2013.

Cell's intracellular temperature has shown to have a vital role in controlling a cell's conditions, properties, activities, and the cell response towards external stimuli. Yet, Current conventional methods are not able to give accurate or any measurements when spatial resolution decreases to a micro scale. Many researches from different field are trying to develop ways that give high accuracy and high temperature sensitivity. We present here a Nano-needle microfluidic system for single cell temperature measurement; however, here we discussed the optimization using finite element approach of the sensor design using tungsten as the electrodes, and semiconducting metal oxide Co3O4 as the sensing material. The dimension of the sensor that gave the highest voltage thus highest sensitivity were ratio 1:4 of element diameter/electrode cross sectional area, a gap of 450nm between electrodes and a penetration depth of 0.25 in electrode 0.25nm. Furthermore, Voltage response gave results to measure a 0.1°C.

The subject of the RailCab project is the development of autonomous railway cabins, which can dynamically group to convoys without mechanical coupling. This enables an on-demand use of these vehicles while retaining the cost and ecological advantages of public transport. In this paper, we present (1) the system concept with focus on the convoy operation mode. Furthermore we explain (2) the system and communication architecture, which is the basis for the coordination and organization of locally distributed systems. The main contribution of this paper is the convoy control system (3). The proposed methods allow automatic and dynamic operation of vehicle convoys. Experimental results from real-life tests (4) validate the system, the communication structure and the control synthesis, thereby ensuring safe and reliable operation.

In this paper, two optimization techniques of Particle Swarm Optimization (PSO) and Firefly Algorithm (FA) is used to obtain the optimal PID control parameters. To represent the model of the system, system identification with ARX model structure is developed. The results are determined by analysis the step response characteristic of the system. It was observed that the performances of PID controller with PSO optimized parameters perform well in position tracking of the pneumatic actuator system.
