It is related to the variational inequality problem, bilinear programming, nonlinear equation. So there is actual meaning and theories value to study how to solve it.In recent years, many algorithms for solving the generalized linear complementarity problem are put forward. But they basically belong to the traditional iterative methods, and may not be efficient since the computing time required for a solution is greatly dependent on the dimension, structure of the problem and the complexity of the algorithm used. Different from the traditional algorithms, the neural network has many advantages on calculations and real-time applications for its inherent massive parallelism and electric circuit implementation.
近年来,人们对广义线性互补问题提出了许多算法,但这些方法基本上属于传统的迭代法,由于它们的计算时间极大地依赖于问题的规模、维数以及所使用的算法,因此很难满足实时并行的要求,与传统数值方法不同,由于内在的并行分布处理信息的特点及电路实现的潜能,神经网络有着许多计算上的优势和实时性的应用,自Hopfield提出著名的人工神经网络模型-Hopfield神经网络,并将其成功应用于优化问题后,用神经网络求解优化问题得到了相当深入的研究,并取得了许多重要的成果。

The project will develop a bandpass sigma-delta analog-to-digital converter for digital audio broadcasting system in three years. In the first year, we had finished the system simulation for IF receiver using conventional high speed ADC and bandpass sigma-delta ADC, respectively. We also had done the analysis and design of high-order bandpass sigma-delta modulator structure. In this year, we have developed a coefficient synthesis method for high order bandpass sigma-delta modulator using high order filter transfer functions (inverse Chebyshev bandreject filter function).

A new way of distance measurement is introduced in this paper, it is similar to traditional measurement way, and has its origination. In the new measurement way, the rough measurement of the distance is realized by countering high frequency pulses filled in discriminable phase pulses. Discriminable phase pulses go through integral circuits, and then are sampled by Analogue Digital Converter, so the accurate measurement of the system is obtained by the sampling value.
本文提出了一种新的测距方法,该方法与常规相位测距仪比较,既有相似之处也有其创新之处,常规相位测距仪一般使用多波长测尺频率组合、差频数字测相的方法,本系统虽然也采用多波长测尺频率组合,但并不采用差频数字测相,该方法摒弃了传统的内外光路的切换方式及电路的混频,粗测采用对鉴相脉冲填充高频脉冲的办法实现,精测则利用鉴相脉冲对积分电路进行积分,然后由ADC 对积分电平进行转换,通过对ADC 的输出值的计算处理实现精测。

The technique made full use of the characteristic of PR controller which can realize zero steady-state error in AC input signal in stationary frame. In the method, the active and reactive current component in the vector control strategy were transformed in the stationary frame to achieve the objective of keeping the DC-link voltage constant, adjusting the power factor and decoupling the active and reactive power. Compared with conventional double close-loop proportional integral controller, the PR technique is better in harmonic compensation without the complex rotating frame transformation and the couple or feedback voltage which is easily influenced by temperature and circuit parameters. The control algorithm is easy to be realized while the robustness and power quality is improved.
