A data acquisition controller based on Complex Programmable Logic Device is designed and implemented in a data acquisition system of high performance downhole acoustic logging tools.

Research on integrated controller of suspension and Steering based on Embedded System;

Specifically,the regenerative braking system(RBS) is incorporated into ABS,the regenerative braking motor takes part in anti lock braking control,the regenerative braking is preferentially adopted as far as possible on the premise of braking safety,and an integrated controller is designed based on TMS320C6713.

By means of the commonly-used domestic variable duration impulse integrated controller, alterna tive design was carried out on PWM control chip of switching power on overseas equipments.
