Abstract
A pressure sense recognition control system having at least one pressure sensor module for detecting the two-dimensional distribution of the component forces in the three directions in the rectangular coordinate system of a force applied to the pressure receiving surface of the pressure sensor modules. The pressure sensor module has at least one pressure sensor cell having a pressure sensing member made of single crystal silicon, and a plurality of diffusion type strain gauges provided on the surfaces of the pressure sensing member which are substantially perpendicular to the pressure receiving surface and for detecting the three component forces applied to the pressure surfaces in response to the changes of an output of a bridge composed of the strain gauges. These members are mounted on an object, the drive of which is to be controlled. The detection signals derived from the pressure sensor module are processed and converted into pressure sense detection data corresponding to the pressure surfaces for each of the component forces. The data is further processed to produce pressure sense recognition data. Data for controlling the drive of the object is obtained from the pressure sense recognition data.
