Asphalt carbon fiber heating process had nonlinear

long time delay characteristics when it was influenced by specific heat and thermal environment.For implementing constant heating rate control of the system

ensur ing pitch carbon fiber material characteristics

a new type of two-dimensional cloud intelligent control algorithm was proposed.Presenting the uncertainty rea soning of control rules based on cloud model

representing a qualitative concept with expected value Ex

entropy En and hyper entropy He

full y considering the fuzziness and randomness in the system

the algorithm establis hed 2-D cloud model of the control with the temperature rate and temperature as main parameters.After getting two cloud droplets by using heating rate control and temperature control rules

control output was got through soft and.Simulat ion results show that the controller can control the heating rate in 20 seconds within the range of ±0.005 ℃/s

and can solve the problem of accumulated error which traditional PID controller can't eliminate.
