ealizing it in Codesys controller algorithm software. ( 3) Designing and running the temperature control system for DSG solar system on the basis of testing platform of Hollysys MACSV software initially, which is inclined to simulate and debug temperature controller, also convenient and fast to observe dynamic operation process and acquire operation result. III After a number of simulation test and online test on testing platform, we can analyze the operation curve and test datas according to stability and accuracy performance index, showing high controllable of vapor stream. The feedback and sliding model algorithm innovative applyment to tempeture control is pletely feasible. The temperature controller is simple and convenient .The steady and antiinterference performance of feedback linearization temperature controller is accessible, the velocity and accuracy performance of sliding temperature controller is more than better, and plementary advantages temperature controller bining both advantages is the best, therefore, the research pletely achieves the subject control requirements.
