Robust MPC of constrained nonlinear systems based on interval arithmetic
A robust MPC for constrained discrete-time nonlinear systems with additive uncertainties is presented. The proposed controller is based on the concept of reachable sets, that is, the sets that contain the predicted evolution of the uncertain system for all possible uncertainties. If processes are nonlinear these sets are very difficult to compute. A conservative approximation based on interval ...
متن کاملRobust MPC of an unstable chemical reactor using the nominal system optimization
The continuous stirred-tank reactor with uncertain parameters was stabilized in the open-loop unstable steady state using the robust model predictive control. The gain matrices of the robust state-feedback controller were designed using the nominal system optimization and the quadratic parameter-dependent Lyapunov functions. The controller was verifi ed by simulations using the non-linear model...
متن کاملRobust constrained MPC stabilization of a CSTR
The paper addresses a case study of robust stabilization of a continuous stirred tank reactor using robust model-based predictive control with constrained input variables. One exothermic reaction runs in the reaction mixture and the reactor is modelled in the form of an uncertain polytopic system. The control approach is based on solution of a set of linear matrix inequalities. This formulation...
متن کاملInterpolation based MPC with exact constraint handling: the nominal case
Interpolation techniques are known to reduce computational complexity of MPC algorithms (Rossiter et al., 2004, Bacic et al., 2003). However, despite giving good feasible regions, there is nevertheless often some conservatism. This paper presents a new insight on general interpolation which reduces this conservatism and hence allows a substantial increase in feasible regions and therefore the p...
متن کاملA Robust Knapsack Based Constrained Portfolio Optimization
Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...
