Hardware generally uses a dial

Initialization u In order for the control system to reach a steady state as soon as possible after power-on, u must be initialized to u should correspond to the stable output of the computer after the system is debugged normally. Before the system is not debugged, if u is not estimated, first take the value of Hua Luogen's 0.618 method. At this time, u≈158, after the system debugging is normal, rewrite the value of u.

The value of the sampling period T. A fuzzy control must have good dynamic characteristics. The sampling interval must be reasonably selected. For a control system with a time constant of T, the sampling period ranges from: This is the only one of the algorithm. A constant that could not be avoided, but this constant has little effect on the algorithm. Even if T is not properly selected at the beginning, the consequence of it is that the system oscillates if the oscillation is u=u±1. For 8-bit D/A converters (0-255), the relative error is small, such as sp Set at the "half" of D/A, the accuracy of 1/127 is better than 1%. If the oscillation exceeds the tolerance range, T needs to be rewritten. It is recommended that the hardware use the dial or keyboard to input T for debugging. The time constant T of the system is not difficult to determine. If necessary, a step pulse can be added to the input end, and then the transition process of the output can be observed to determine T. The crusher power controller T developed by the author is approximately equal to 1 s.

Due to the use of AutoCAD drawing and high-speed CNC milling machine processing, the grid positioning is accurate and the machining accuracy is high. If a laser grating is used to etch the grating grid, the accuracy can be further improved. Since the machining errors in the grid making process are randomly distributed, there is no cumulative error. In theory, the measurement accuracy can be increased infinitely through system expansion. The large stroke displacement measuring device has the characteristics of low cost, easy realization, high precision and high reliability. (Finish)
