this paper presents h∞ control problem for input-delayed systems. a neutral system approach is considered to the design of pd controller for input delay systems in presence of uncertain time-invariant delay. using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. the significant specification of this neutral system is that its delayed coeff...

When models are inaccurate, the performance of model-based control will degrade. For linear quadratic control, an event-triggered learning framework is proposed that automatically detects inaccurate and triggers a new process model when needed. This achieved by analyzing probability distribution cost designing trigger leverages Chernoff bounds. In particular, whenever empirically observed signa...

Communication and control co-design for networked control system in optimal control in the paper. Under p – to – wσ communication sequence which sensors access communication medium and m – to – wρ communication sequence which actuators access communication medium, the plant of networked control system acts as a linear periodic time-varying system. Using lifting technology, a linear periodic tim...

Optimal multirate control of the networked control systems is investigated in this paper. Under p – to – wσ communication sequence that sensors access communication medium and m – to – wρ communication sequence that actuators access communication medium, the plant of networked control system acts as a linear periodic time-varying system. Using lifting technology, a linear periodic time-varying ...

The threat of climate change and diminishing fossil fuels demands nothing short of an energy revolution, a transformation which is already underway as renewable energy markets exhibit enormous and steady growth. This paper presents design of optimal control schemes for Wind Energy Conversion Systems (WECS) based on a time scale technique. The dynamics governing the mechanical components of a va...

The predictive pole-placement control method introduced in this paper embeds the classical pole-placement state feedback design into a quadratic optimisation based model-predictive formulation. This provides an alternative to model-predictive controllers which are based on linear-quadratic control. The theoretical properties of the controller in a linear continuous-time setting are presented an...

The paper establishes a new procedure to obtain the solution for the optimal tracking problem based on dynamic programming. The optimal control refers to a quadratic criterion with finite final time, regarding a perturbed time-variant linear system. The proposed algorithm can be easier implemented by comparison with other procedures. Key-Words: optimal control, linear quadratic, tracking problem
