in this paper, firstly by using a mixed linear programming a new model of locating facilities with limited capacity is presented to design a closed-loop supply chain in a multi-product and multi-period mode. then, using a robust optimization approach, the proposed model decreases in non-deterministic expansion. the results show that the proposed model can handle facility capacity in a closed lo...

to enhance the closed loop performance in presence of disturbance, uncertainties and delay a double loop mixture of mpc and robust controller is proposed. this double loop controller ensures smooth tracking for a 3-axis gyro-stabilized platform which has delay intrinsically. this control idea is suggested to eliminate high frequency disturbances and minimize steady state error with minimum powe...

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

This paper continues the discussion of the detailed experimental study conducted on adaptive optical control methodologies inside a laser resonator.(1) In this paper we discuss the experimental results for the correction of tilt within a laser resonator utilizing a multidither zonal COAT system. The tilt aberration was introduced in three different ways: (1) static tilt was introduced while the...

This paper provides a framework for control design and simulation of a closed-loop system with partial input/output data of a plant. Given the input/output crosscorrelation and output autocorrelation data of an open loop dynamic system, a simulation model implemented in fixed-point digital devices which matches these data is obtained using q-Markov Covariance Equivalent Realizations. These resu...

In this paper we present a general framework for closed-loop subspace system identi cation. This framework consists of two new projection theorems which allow the extraction of nonsteady state Kalman lter states and of system related matrices directly from closed-loop input output data. Three algorithms for the identi cation of the state space matrices are then presented. The similarities betwe...

In this paper, it investigate the bit error rate (BER) performance of transmit beamforming using singular value decomposition (SVD) for closed loop multiple-input multiple-output (MIMO) wireless systems with various modulation techniques such as binary phase shift keying (BPSK), quadrature phase-shift keying (QPSK)‎ and 16quadrature amplitude modulation (16-QAM) along with convolution encoder a...
