Abstract: In this paper a new intelligent mechatronic system for automatic gates is presented.
Considering the cost and hardware constraints, satisfy the strict European rules
both for the dynamic force and for the reaction time in case of impact with an obstacle
is a non trivial problem. The developed solution solves this problem exploiting
a unique sensor and working in two phases. In the first phase of autotuning, the
main mechanical parameters of the system are recognized. In the operative phase,
the door is controlled and operated with the highest allowable speed. Moreover the
overall procedure is able to recognize and adapt the control to the different operative
conditions estimating the mechanical values and operating the motor consistently.
High efficiency, safety and low cost requirements are taken into account in the development of the solution and the experimental results confirm the effectiveness of
