J. Prakash, Auteur ; Sachin C. Patwardhan, Auteur ; Sirish L. Shah, Auteur |Recursive estimation of states of constrained nonlinear dynamic systems has attracted the attention of many researchers in recent years. In this work, we propose a constrained recursive formulation of the ensemble Kalman filter (EnKF) that retai[...]

Muddu Madakyaru, Auteur ; Anuj Narang, Auteur ; Sachin C. Patwardhan, Auteur |Among various industrial vendors of model predictive control (MPC) schemes, ARX appears to be a popular choice of model structure while models for predictive control schemes are being developed. These models are, however, nonparsimonious in the [...]

Shraddha Deshpande, Auteur ; Sachin C. Patwardhan, Auteur ; Ravi Methekar, Auteur |Nonlinear model predictive control (NMPC) is increasingly being used for controlling microscale and system-on-chip devices, which exhibit complex and very fast dynamics. For effective control of such systems it is necessary to develop computatio[...]

Rui Huang, Auteur ; Lorenz T. Biegler, Auteur ; Sachin C. Patwardhan, Auteur |To deal with plant−model mismatches in control practice, this paper proposes two variations of an offset-free framework which integrates nonlinear model predictive control (NMPC) and moving horizon estimation (MHE). We prove that the proposed me[...]

Kishalay Mitra, Auteur ; Ravindra D. Gudi, Auteur ; Sachin C. Patwardhan, Auteur ; Gautam Sardar, Auteur |Uncertainty issues associated with a multisite, multiproduct supply chain planning problem has been analyzed in this paper, using the chance constrained programming (CCP) approach. In the literature, such problems have been addressed using the s[...]

Anjali P. Deshpande, Auteur ; Sachin C. Patwardhan, Auteur |Many chemical processes exhibit highly nonlinear dynamic behavior when operated over a wide operating range. The fault diagnosis schemes based on a linear perturbation model often prove to be inadequate, with regard to addressing fault diagn[...]

Anjali P. Deshpande, Auteur ; Ujjwal Zamad, Auteur ; Sachin C. Patwardhan, Auteur |In processing plants, sensor and/or actuator failures can have considerable deteriorating effect on the closed-loop performance. Such failures have to be diagnosed online, as quickly as possible, and actively accommodated to arrest the performan[...]

Kishalay Mitra, Auteur ; Ravindra D. Gudi, Auteur ; Sachin C. Patwardhan, Auteur |Integration of scheduling and control in process manufacturing systems has traditionally resulted in greater coordination between the different layers of hierarchy in optimization and control. However, the effectiveness of this coordination as w[...]
