Analysis and methods for control of objects with quasi-static time-dependent characteristic - objects with elastic and plastic static characteristic

This paper presents an approach for a special class of objects. Objects with elastic static characteristic change their characteristic depending on the rate of change of the object´s input coordinates. An example of objects with elastic characteristic would be an inflated construction. The motion trajectory of the material point that possesses weight on this construction depends on the rate of change of the coordinates. A control system for similar objects must be supplemented with a special correction element that changes the parameters of the main system depending on the rate of change of the main system´s outputs. Objects with plastic static characteristic change their characteristic in the zone where the objects´ input signals coordinates are located. An example of such objects is objects that are sensitive to wear, e.g. working zone of mechanical objects and senescent objects, biological objects, etc. A control system for such objects must be supplemented with the plastic static characteristic model. This subsystem will change the control system´s main parameters based on the input signals´ trails depth.
