Abstract

Method (100) for controlling the stability conditions of a machine (1) moveable on a ground (G) having at least an operational component (2), in particular a hydraulic cylinder, for moving a portion (3) of the machine (1), and being maneuvered by an operator through operational commands, the method (100) comprising acquiring (S101) at least a first sensor signal (4) defining the position of the portion of the machine (1); acquiring (S102) at least a second sensor signal (5) defining a variation of the position of the portion of the machine (1) relative to the ground (G); acquiring (S103) at least a command signal (6) defining the operational commands of the operator for actuating the operational component (2) and for transmitting an operational velocity to said portion (3) of the machine (1); determining (S104) a stability condition of the machine (1) based on the first sensor signal (4), the second sensor signal (5) and the command signal (6), and outputting (S105) a control signal (7) to control the operational component (2) as a function of the determined stability condition, wherein the stability condition is determined by monitoring and estimating both the static and the dynamic stability conditions of the machine (1), in particular by monitoring and estimating the position of the center of gravity and of an index of stability of the machine (1), relative to a contact area of the machine (1) with the ground (G).
