Abstract

The discrete time preview control problem is investigated in this paper in the framework of frequency characteristics. Along this line, the most attractive is the Zero Phase Error Tracking Controller, abbr., ZPETC, which can reduce the phase characteristics of the overall system to zero for all frequencies. However the previous methods may produce an excessive gap between the gain of the overall system and unity, which is ideal gain characteristics. This paper proposes a new ZPETC, which is designed so as to minimize the maximum of the gain gap over a specified frequency range under the condition of zero phase error. Our contribution is that the proposed ZPETC can bring the gain of the overall system closer to unity than the previous methods, which is demonstrated by a numerical example.
