Simulating a simscape model in real time requires a balance of speed and accuracy that you can attain by reducing computational costs, optimizing solver. Use the diff function to approximate partial derivatives with the syntax y difffh, where f is a vector of function values evaluated over some domain, x, and h is an appropriate step size. To estimate how long a portion of your program takes to run or to compare the speed of different implementations of portions of your program, use the stopwatch. The electric circuit of the armature and the freebody diagram of the rotor are shown in the following figure. Du kannst dateien in diesem forum posten du kannst dateien in diesem forum. However, testing the output with a number like 77777777777777777 doesnt make much sense, since this is a larger integer than what a double the default matlab type can hold.
