As a result of the optimal control with SEOS oscillations of the mast and waiting periods are eliminated and the acceleration is increased. These measures increased the throughput of existing plants by 40%.
With SEOS vibrations of the stacker crane can be avoided. Even at dynamic speeds with high acceleration the movement is smooth and well-controlled. The mechanical factor of safety of conventional systems could be increased by 1.5 times.
Through the combination of a precise forecast calculation of the mast movement and an anti-vibration controller, the waiting times of existing plants could nearly be eliminated. After arriving at the target position the average waiting times were 0.1 seconds.
Conventional drive control systems usually achieve an oscillation coefficient of 1.5. With the SEOS technology this coefficient can be reduced to 1.05. Hence, the mechanical stress of the stacker crane is lowered and performance improvements are possible.
SEOS automatically accelerates and decelerates the stacker crane in an intelligent way. Since vibrations are avoided, the mechanical cyclic stress at existing plants could be reduced by 35%. Hence, mechanical components are protected and the wear and tear is reduced.
Shorter movement times and a reduction of peak loads lead to a lower energy consumption. On existing plants the energy consumption could be reduced by 1/4. The combination of SEOS and particularly tuned mast designs can further lower energy consumption.
A precise forecast calculation of the mast movement and an anti-vibration controller eliminate vibrations and enable a load and time optimal control of the stacker crane. Hence, with SEOS the acceleration of conventional plants could be increased by 233%.
Since vibrations can be avoided with SEOS, it is possible to increase the construction heights of conventional mast designs by 40%. This enables lightweight designs of stacker cranes and a reduction of construction costs.
With conventional drive control systems the commissioning engineer usually has to adjust the control parameters by extensive trial and error. In contrast, SEOS can automatically estimate optimal parameter settings via its integrated modelling and optimization. This saves both time and money.
