In this paper a continuous-time state-space aerodynamic model is developed based on the boundary element method. Boundary integral equations governing the unsteady potential flow around lifting bodies are presented and modified for thin wing configurations. Next, the BEM discretized problem of unsteady ...
In view of the above issues, in this work the problem of deriving continuous-time LPV models in state-space form from sampled measurements of input, output and scheduling variables is considered, in the framework of a local approach. The proposed method is formulated in the subspace model ...

Maximum likelihood parameter estimation of the continuous time linear stochastic state space model is considered on the basis of largeN discrete time data using a structural equation modeling (SEM) program. Random subject effects are allowed to be part of the model. The exact discrete model (EDM)...
You can create a state-space model object from a linearized model using thess(Control System Toolbox)function. You can use state-space model objects to represent a linear time invariant (LTI) system for control design. You can also combine multiple LTI state-space models to represent more com...

Without the subscript, the model is time invariant—the parameters and variables are the same throughout the sample period. Regardless of your application, a goal of state-space modeling is to estimate and analyze the latent states xt and model parameters Θ. With Econometrics Toolbox you can ...

This becomes even more troublesome as the complexity of the data, task and state space increases (that is, requiring more precision)11, for instance, in open-world problems such as medical data processing, self-driving cars, financial time-series and physics simulations. The research community ...
