연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A system and method of providing floating actuator control is provided. This system and method receives input command signals from an actuator controller, and effectively integrates these signals until the controller has requested a large enough movement of the actuator that the actuator can actually effectuate. At this point, the system and method drive the actuator to the commanded position. As a result, excessive mechanical wear in the actuator caused by small command signal perturbations and dither is reduced or eliminated.

1. A method of controlling an actuator, comprising the steps of:receiving at least one of an actuator close command and an actuator open command from an external primary controller; accumulating information relating to a duration of the at least one of the actuator close command and the actuator open command; and delaying driving the actuator until the accumulated information exceeds a predetermined threshold. 2. The method of claim 1, wherein the step of driving the actuator when the accumulated information exceeds the predetermined threshold comprises the step of setting the predetermined threshold to a time value that provides an effective control response from the actuator.3. A method of controlling an actuator, comprising the steps of:receiving at least one of an actuator close command and an actuator open command from an external primary controller; accumulating information relating to a duration of the at least one of the actuator close command and the actuator open command; driving the actuator when the accumulated information exceeds a predetermined threshold; wherein the step of driving the actuator when the accumulated information exceeds the predetermined threshold comprises the step of setting the predetermined threshold to a time value that provides an effective control response from the actuator; and wherein the step of accumulating information relating to the duration of the at least one of the actuator close command and the actuator open command is processed a predetermined number of times per second, and wherein the step of accumulating information comprises the steps of increasing a count by an integer when one of the actuator close command and the actuator open command is received and decreasing the count by the integer when the other of the actuator close command and the actuator open command is received. 4. The method of claim 3, further comprising at least one of the steps of adding a count of opposite polarity of the count added during the actuator close command during the step of driving the actuator closed and adding a count of opposite polarity of the count added during the actuator open command during the step of driving the actuator open.5. The method of claim 4, further comprising the step of stopping the actuator when the count reaches zero.6. A method of controlling an actuator, comprising the steps of:receiving at least one of an actuator close command and an actuator open command from an external primary controller; accumulating information relating to a duration of the at least one of the actuator close command and the actuator open command; driving the actuator when the accumulated information exceeds a predetermined threshold; and further comprising the step of reducing the accumulated information during the step of driving. 7. A method of controlling an actuator, comprising the steps of:receiving at least one of an actuator close command and an actuator open command from an external primary controller; accumulating information relating to a duration of the at least one of the actuator close command and the actuator open command; driving the actuator when the accumulated information exceeds a predetermined threshold; and further comprising at least one of the steps of disabling further accumulation of information relating to the duration of the actuator close command when the actuator is stalled closed, and disabling further accumulation of information relating to the duration of the actuator open command when the actuator is stalled open. 8. The method of claim 7, further comprising at least one of the steps of clearing the accumulation of information relating to the duration of the actuator close command when the actuator is stalled closed, and clearing the accumulation of information relating to the duration of the actuator open command when the actuator is stalled open.9. A method of controlling an actuator, comprising the steps of:receiving at least one of an actuator close command and an actuator open command from an external primary controller; accumulating information relating to a duration of the at least one of the actuator close command and the actuator open command; driving the actuator when the accumulated information exceeds a predetermined threshold; and wherein the step of driving the actuator when the accumulated information exceeds a predetermined threshold comprises the step of driving the actuator when the accumulated information indicates that one of the actuator drive open command and the actuator drive close command has accumulate to approximately one second. 10. A floating actuator control system for use in a heating, ventilating, and air conditioning (HVAC) system, comprising:a damper providing a variable opening to allow fluid communication from the HVAC system to a zone; a primary zone temperature controller positioned to sense ambient temperature of the zone, the primary zone temperature controller generating a damper close command and a damper open command, the primary zone temperature controller allowing the damper close command and the damper open command to float when movement of the damper is not required; an actuator drivably coupled to the damper; and a floating actuator controller operatively coupled to the actuator, the floating actuator controller configured to receive the damper close command and the damper open command from the primary zone temperature controller; and wherein the floating actuator controller receives at least one of the damper close command and the damper open command from primary zone temperature controller, accumulates information relating to a duration of the at least one of the damper close command and the damper open command, and drives the actuator when the accumulated information exceeds a predetermined threshold. 11.
