By the c mbi nati n f the different l ps and valve p siti n, the system is a multivariable, c upling, disturbance and multiple w rking c nditi n c ntr lled bject . C mmunicati n hardware has the functi n f serial c mmunica ti n, signal A/ D and D/A. C ntr l s ftware is pr grammed by VC++ , and c ntr l alg rithm is an inde pendent m dule, and revise and add f c ntr l alg rithm is easy. The c ntr l system has high integrati n, perfect functi n and userfriendly interface. The experimental results sh w that the system is a perfect exper iment platf rm f r c ntr l alg rithm validati n.
