Control method of multivariate systems based on probability control algorithm

Compressor refrigerating capacity test system is a multivariate system. In accordance with the dynamic distributive parameter mathematical models, this paper puts forward a kind of digital-pulse conversion that regards the random function as the core and the probability control technique described with condition probability. Probability control technique and other control tactics are used for operating conditions. These control tactics are proposed for improving the control precision and the robustness of the system, and speeding up the response process of the test system. A practical application shows that these control technique have better control effect.
