用MC33035搭配AD5621驱动直流无刷电机,采用增量式PID速度闭环控制,为什么电机高速(600rpm以上)运行误差小,低速(600rmp以下)误差大?

alc5621谁用过?我用的时候容易把单片机烧坏是什么原因?

自动增益控制(AGC)电路在很多应用中都非常重要,例如频率合成器的幅度稳定、发射机输出功率控制或接收机动态范围优化。图1所示电路采用ADL6010检波器、HMC985A电压可变衰减器(VVA)和HMC635 RF放大器,在很宽的输入频率(20 GHz至37.5 GHz)和幅度范围内提供自动增益控制。

你好,我设置psoc63进入休眠与唤醒触发运行RTC模式。与Keysight n6705c功率分析仪测量4µ我在休眠模式。期望值是800 Na Hibernate + 380 Na RTC(运行与生态)= 1.18µA.我连三V PWR引脚(删除跳线J8)在PSoC六BLE创业板背面连接GND的功率分析仪对董事会的任何引脚。我看了图,我看不到任何其他现有的绘图装置,连接销的压水堆。这是正确的测量程序,我可以做我的功率分析仪?我必须用功率分析仪的准确测量和做一个可靠的即其他芯片。我将所有的低频时钟的时钟和世界海关组织禁用调试引脚GPIO和没有主要用在所有。我启用了0.9 V SIMO降压。这个项目做了以下:-醒来的RTC每3秒-广告等待5ms广告做的把系统恢复到休眠你知不知道我可能忘记关闭?当进入休眠模式,我必须显式禁用任何块?谢谢您!以上来自于百度翻译 以下为原文Hello, I am setting the PSoC63 into the Hibernate mode with running RTC for wake-up triggering. With a Keysight N6705C power analyzer I measure 4 µA in Hibernate mode. Expected value was 800 nA Hibernate + 380 nA RTC (running with ECO) = 1.18 µA. I connect 3 V to the PWR pin (removed jumper j8) on the backside of the PSOC 6 BLE Pioneer board and connect GND of the power analyzer to any GND pin on the board. I looked in the schematics and I dont see any other current drawing device which is connected the the PWR pin. Is this the correct measurement procedure I can do with my power analyzer? I have to use the power analyzer for accurate measurements and do a reliable comaprison to other chips. I reduced all LF clocks to the WCO clock and also disabled debugging pins to GPIO and no GPIOs are used at all. I enabled the 0.9 V SIMO buck. The project does the following: - Wake up from RTC every 3 seconds- Advertisement- Wait 5 ms for Advertisement done- Put system back to hibernate Do you have any idea what I could have forgotten to disable? When entering Hibernate mode, do I have to explicitly disable any blocks? Thank you!
