(2) The control and setting of centrifugal pump’s flow and pressure. (2 credit hour)
Based on critical proportion method and the decay method, set the PID control system of centrifugal pump, observe the effect of the PID parameter on the quality of transient process by setting different proportion rate, integral time and derivative time.
Assignment
Arrange and collect assignments Weekly, assignments include about 30 questions;
The result of assignments account for ten percent of final result.Times of late or lacking homework should be less than twenty percent of total times, otherwise it will affect final result.
Promote and encourage students to discuss the homework assignments, but eventual assignments must be finished independently, copying other clas**ates’ homework will violate academic morality, serious case will be handled by the students discipline committee.
Finishing homework carefully will be very helpful to grasp teaching contents and get good grades of the quizzes and final exam, because test paper may contain the homework assignments.
Evaluation Approaches
This course has five in-class quizzes approximately 10 minutes in length without prior notice, which will be included in class performance (assignments and attendance). Final exam runs for 120 minutes. Specific exam time will be noticed at least 2 weeks in advance. The evaluation of students' experimental grades is mainly according to the experimental attendance and the quality of the experimental report.
Asses**ent System
Final result consists of three parts: peacetime result（15 %）, experimental result（5 %）, final result（80 %）, peacetime result is decided by assignments, quizzes and attendance.
