[Mathimatics-Numerical algorithms] PID-c-source-code DL : 0: 在使用单片机作为控制cpu时，请稍作简化，具体的PID参数必须由具体对象通过实验确定。由于单片机的处理速度和ram资源的限制，一般不采用浮点数运算，而将所有参数全部用整数，运算到最后再除以一个2的N次方数据（相当于移位），作类似定点数运算，可大大提高运算速度，根据控制精度的不同要求，当精度要求很高时，注意保留移位引起的“余数”，做好余数补偿。这个程序只是一般常用pid算法的基本架构，没有包含输入输出处理部分。-In the use of single-chip microcomputer as the control cpu, please make some simplification, the specific PID parameters must be determined through experiments at specific audiences. As the single-chip processing speed and ram resource constraints, generally do not use floating-point, and will use all parameters of all integers, computing the final 2 and then divided by a N-th power of data (equivalent to shift), similar fixed-point computation can be greatly enhanced speed of operation, according to the different requirements of control precision, when high precision, the attention to retain the shift caused by the balance , do a good job in the balance of compensation. This procedure is commonly used algorithm pid basic structure does not contain input and output part of treatment.

The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. At the inlet, a Poiseuille profile is imposed on the velocity, where as the outlet implements an outflow condition: grad_x p = 0. At Reynolds numbers around 100, an unstable periodic pattern is created, the Karman vortex street.

[Mathimatics-Numerical algorithms] ProjectCode DL : 0: The objective is to find out the time at which the rocket reaches a speed of 1000m/s (3600km/hr). Analysis We know the following: * Initial mass of the rocket and fuel, 160000kg, or 160 metric tons. * Fuel combustion exhaust velocity relative to the rocket is assumed to be constant at 2200m/s * Fuel combustion rate is a constant 2680kg/sec2 * Gravitational acceleration is 9.8m/sec2 The following formula is used to calculate the upward velocity of the rocket while the fuel is providing thrust: V = u*loge(m0/(m0-qt))-g*t Now substituting the values in the formula we get: 1000 = 2200*log(160000 / (160000 – 9.8*t)) – 9.8*t which is too difficult to solve analytically so we use Bisection root-finding method. The source code is for a program that solves this problem with the given parameters.
