We formulate an optimization problem to obtain the combined sequence of waveform parameters (pulse amplitudes and lengths, and FM sweep rates) and detection thresholds for optimal target tracking in clutter. The optimal combined sequence minimizes a tracking performance index under a set of parameter constraints. The performance index can include the probability of track loss and the estimation accuracy. The effect of the false alarms and clutter interferences is taken into account in quantifying the performance index. A measurement model is developed based on the resolution cell in the delay-Doppler plane for a Gaussian pulse. Numerical experiments were performed to solve the optimization problem for several example problems.

The probabilistic data association filter (PDAF) is known to provide better tracking performance than the standard Kalman filter (KF) in a cluttered environment. In this paper, the stability of the PDAF of Fortmann et al. (1985), in the presence of uncertainties with regard to the origin of measurement, is investigated. The modified Riccati equation derived by approximating two random terms with their expectations is used to evaluate the stability of the PDAF. A new Lyapunov function based approach, which is different from the quantitative evaluation of Li and Bar-Shalom (1991), is pursued. With the assumption that the system and observation noises are bounded, specific tracking error bounds are established.
已知概率数据关联滤波器(PDAF)在混乱环境中比标准卡尔曼滤波器(KF)提供更好的跟踪性能。本文研究了Fortmann et al.(1985)在测量原点存在不确定性的情况下PDAF的稳定性。用修正的Riccati方程逼近两个随机项及其期望，来评价PDAF的稳定性。与Li和Bar-Shalom(1991)的定量评价不同，本文提出了一种新的基于Lyapunov函数的方法。在假设系统和观测噪声有界的情况下，建立了具体的跟踪误差界。

A robotic manipulator for eating assistance is proposed. The manipulator system can move a spoon in the three orthogonal directions. The manipulator system can also rotate and withdraw the spoon in order to dip into food easily. An easy human interface using a head space pointer and a personal computer display has been designed. A user can operate the robotic manipulator by his/her head movement and puff. A user can operate the robotic manipulator by selecting many commands listed on the display.

Presents an adaptive speed controller for field-oriented-controlled (FOC) permanent magnet synchronous motor (PMSM) drives. However, achieving FOC requires machine specific knowledge, and tracking of drifting motor parameters in order to maintain control. The proposed controller, based on the minimum controller syntheses (MCS) algorithm, does not require exact knowledge of motor parameters. This controller structure simplifies the design and implementation of the adaptive controller requiring less effort to synthesise than a standard MRAC system. The paper presents the simple current controller with three level comparator and the experiment results. It is shown through experiment that the proposed controller is insensitive to motor saturation and parameter variations.

Instead of an RF module which has been used conventionally in many remote measurement applications, a new type of remote measurement system for oceanic environments based on a PCS and a one chip microcontroller is proposed. PCS has many advantages with respect to cost, reliability, communication quality, and so on. The proposed system consists of four different modules: PCS module, microcontroller module, GPS module, and sensor module. System configuration as well as an illustrative experiment are described in detail.

In recent years MHT (multiple hypothesis tracking) attracts much attention because of its tracking performance. MHT has heavy computation load problem and an approach for computation time reduction by applying N-best algorithm was reported. We have improved the function of MHT and named the improved algorithm as track oriented MHT. It has different data structure from original Reid's MHT d(1984), so N-best algorithm can not be applied to it straightforwardly. We show the applying method of N-best algorithm to track oriented MHT. And also we show the efficiency of the method by comparing the computation time in a simulation.

The aim of the study is the development of an automatic chloride film detector for use in the treatment of waste garbage plastics i.e. Sanuki RDF System against Dioxins. The method used is pattern matching using a blue light absorption detecting method for the transparent chloride plastic film of garbage wrapping using a two dimensional FFT analyzer instead of X-ray or CuCl/sub 2/ green flame methods. The paper describes the reason for the absorption of the blue flame is the plasticizer agent in PVDC (polyvinyl dichloride) or PVC (polyvinyl chloride) film and describes the film heating in a micro wave cooker. The plasticizer will go into the cooked food.

Three-level inverters have superior characteristics relative to traditional two-level inverters. This paper compares the simulation results, using Simulink in conjunction with MATLAB software, with the experimental results of a three-phase three-level inverter implemented to control a three-phase induction motor.
