| Abstract: | The computational delay and its effects on system capabilities in closed loop velocity measurement and control system are analyzed. A novel simplified computational method of velocity measurement is introduced, considering the characteristics of line number of encoders. On the precondition that the resolution is guaranteed, this simplified method reduces the computational workload, shortens the computational time, increases the sampling frequency, extends the measurement scope, and then obtains successful application in the closed loop velocity control system of special type mobile machinery shop. |
