Title:
CONTROLLER FOR KEEPING HORIZONTAL ATTITUDE
Document Type and Number:
Japanese Patent JPH0460816
Kind Code:
A
Abstract:
PURPOSE:To always keep a control object in the horizontal attitude state by detecting the extent of deviation of the attitude of the control object form the horizontal attitude state and reading out manipulated variable data, which is preliminarily set corresponding to this angle based on fuzzy inference, from a memory and driving an angle control mechanism to control the control object. CONSTITUTION:A supporting pole 4 stood on a truck 3 freely shakably supports a placing plate 6 of a liquid vessel by its front end. The deviation of the placing plate 6 from the horizontal plane is detected by angle sensors 13a and 13b, and corresponding manipulated variable data is read out, and a driving current is outputted to servo motors 8a and 8b. Directions and speeds of rotation of servo motors in this case are set correspondingly to the preceding angle and the present angle based on fuzzy inference, and servo motors 8a and 8b are operated in such direction that the placing plate 6 is kept in the horizontal state. Thus, the control object is controlled to the horizontal attitude state.
