After COPS on December 1997, the Co-Generation System(CGS)/Combined Heat and Power(CHP) system is focused on. The environmental influences should be considered on installation, together with the total energy efficiency. The objective of this R&D is to develop the advanced Active Noise Control (ANC) system for the exhaust gas noise from engine in COS. The new concept is based on the system by using the engine rotation angle instead of the initial reference noise. In order to realize this concept, "Frequency Domain Simultaneous Equations Method" and the other expandable algorithm are adapted numerically. As a result, we can show a new direction to higher performance and lower cost ANC, which can be free from a microphone detecting the reference noise and require less labor in the initial turning.
