The tolerating capability of imprecision

uncertainty or inaccurate information in soft-computation makes the combination of members in soft-computation

as well as the combination of soft-compution method with other method to be a new method for solving the complex problems in modeling

control

and optimization of the thermal system.For the effective and reliable output capacity of the ball mill coal-pulverizing system

a soft-measuring model of ball mill's output capacity has been established on the basis of neural network and chaotic information processing technology.Results of simulation show that the said model not only can predict the output capacity under steady state

but also can estimate the on-line out-put capacity of the ball mill in dynamic process.
