PERFORMANCE OF FUNCTION RELATIONSHIP WITH TREND BY SELECTIVE ACTUATOR

We use air conditioner or heater when driving a car in a hot summer or a cold winter. When you want a straight air blow or air conditioning only for the lower bottom, all these air movements are controlled by an actuator. In this thesis paper, we will look into characteristics, pros and cons of DC motor and STEP motor, actuator's sources of energy; correlation between OEPN-LOOP SYSTEM and CLOSED-LOOP SYSTEM; type of mechanics simulation programs of actuator; and characteristics of automotive air conditioner actuator.
