To simluate the effects of lunar dust environment veritably by using lunar dust effects simulator, a detection and control system based on singlechip microcomputer was developed. In this system, peripheral circuits with stepper motor driver, temperature sensor and rotary transformer were used to collect the signals and control the temperature as well as speed. Stepper motor speed up/down curve, digital convolution filter and error compensation were adhibited for improving the system accuracy. The results showed that this method was simple, reliable and had high control accuracy. |
