PID控制仿真程序 假设一个控制系统：10kg的水，使用最大1kW的电阻丝加热，简化计算，假设焦耳和卡的转化单位为1，而不是4.2加热效率为 Watt [瓦],散热效率为5*T [瓦]设定目标温度为60度， 则100000秒内的温度变化曲线是如何的？-PID control simulation program assumes that a control system: 10kg of water, using hot-filament maximum 1kW resistor to simplify the calculation, assuming the conversion of Joule and card unit of one, instead of 4.2 for heating efficiency Watt [W], thermal efficiency of 5* T [W] set a target temperature of 60 degrees, then the 100000 sec the temperature curve is how?

Linux操作系统的著名硬件加速绘图API软件。可以利用网卡提供的硬件加速功能完成绘图，速度比传统的framebuffer要快。-Well-known Linux operating system software, hardware-accelerated graphics API. Can use the card provided by the completion of graphics hardware acceleration, faster than the traditional framebuffer to be fast.
