使用北京大学的代表分析低能π-核子散射的S波和P波相移，将其分解为极点或分支切口的各种项。 我们借助于相对论性重子手性扰动理论中推导的树级扰动幅度，估计左切贡献，直到$$ \ mathcal {O}（p ^ 2）$$ O（p2）。 结果发现，在$$ S_ {11} $$ S11和$$ P_ {11} $$ P11通道中，已知共振和切角的贡献远远不足以饱和实验相移数据–强烈表明低极点的贡献 之前尚未发现，我们将全面探讨其背后可能的物理学。 另一方面，在其他渠道中未发现严重分歧。

应用双级矩阵变换器逆变级在dq坐标系下的合成矢量模型,对双级矩阵变换器提出了具有解耦功能的基于复数PI控制器的电压电流双闭环控制策略,其中针对电压外环和电流内环分别设计了复数PI控制器实现对输出电压和输出电流的控制,并用Simulink建模.仿真结果表明,基于复数PI控制器的电压电流双闭环控制方法不仅能够实现解耦控制,而且可有效地改善双级矩阵变换器的动静态性能及抗扰能力.

在分析无刷直流电机数学模型的基础上，建立了控制系统的仿真模型，提出了一种新型的模糊PI智能控制方法。在无刷直流电机双闭环调速系统中，电流控制采用滞环电流调节器，而转速控制通过采用常规PI控制和模糊控制相结合的方法实现。基于System Generator的仿真结果表明：这种新型的模糊PI智能控制方法响应快、无超调、鲁棒性强、抗干扰能力好，较传统PI控制具有更好的动、静态特性。

针对传统电流控制策略存在高稳态精度与快速动态响应的矛盾,提出了一种基于LCL型有源电力滤波器的复合电流控制策略。该控制策略将比例积分控制和重复控制有机结合,在保证动态响应的基础上,利用PI控制器将控制模型补偿为稳定系统,使其在低频段具有良好的控制特性;利用重复控制器校正LCL型滤波器谐振峰和内环的固有相位滞后,实现电网谐波电流的快速跟踪与高精度补偿。实验结果表明,经过并联有源电力滤波器的谐波补偿,电网电流的总谐波失真明显减小,负载变化时并联有源电力滤波器可实现单周期快速响应,验证了所提出的复合电流控制策略的有效性。

为提高煤矿机车的安全持续性,提高其运行稳定性,在分析无刷直流电机控制系统的基础上,采用一种基于PI控制的双闭环新型无刷直流电机控制系统。采用的双闭环系统中,速度环和电流环都采用PI控制算法,并用MATLAB\Simulink进行仿真验证。结果表明,此系统鲁棒性好、响应速度快,证明了设计的合理性。

Delve into the Broadcom VideoCore GPU used on the Raspberry Pi and master topics such as OpenGL ES and OpenMAX. Along the way, you’ll also learn some Dispmanx, OpenVG, and GPGPU programming. The author, Jan Newmarch bumped into a need to do this kind of programming while trying to turn the RPi into a karaoke machine: with the CPU busting its gut rendering MIDI files, there was nothing left for showing images such as karaoke lyrics except for the GPU, and nothing really to tell him how to do it. Raspberry Pi GPU Audio Video Programming scratches his itch and since he had to learn a lot about RPi GPU programming, he might as well share it with you. What started as a side issue turned into a full-blown project of its own; and this stuff is hard. What You'll Learn Use Dispmanx and EGL on Raspberry Pi Work with OpenMAX and its components, state, IL Client Library, * * Buffers, and more on RPi Process images and video on RPi Handle audio on RPi Render OpenMAX to OpenGL on the RPi Play multimedia files on the RPi Use OpenVG for text processing and more Master overlays Who This Book Is For You should be comfortable with C programming and at least some concurrency and thread programming using it. This book is for experienced programmers who are new or learning about Raspberry Pi.
