This paper presents an overview of the subspa e identif ation problem in open loop. There are several algorithms that solve this problem (MOESP, DSR, N4SID, CVA). Based on the methods MOESP and N4SID the authors propose an alternative algorithm to identify deterministic systems operating in open loop. Two simulated process, one SISO and one MIMO are used to show the performance of this algorithm.
