A modified internal model control method based on static decoupling for non-square processes with right half plant zeros and multiple time delays is proposed. The coupled problems of non-square processes are solved by used pseudo-inverse of steady-state gain matrix. Internal model controller is also applied to Smith delay compensator directly by using equivalence between internal model control ...

This article presents an anterior, minimally invasive surgical approach to the hip joint, aligned along an inter-nervous plane. Positioning in lateral decubitus position on a regular operation table obviates the need for a special orthopedic or fracture table. Traction is not applied. Most of the instruments used for this procedure are standard instruments for reaming of the acetabulum and posi...

In order to solve the current difficulties of modeling for designing Intelligent Service Mobile Robot (ISMR), a new modeling method based on metasynthesis is proposed from the macro and micro levels. And the system analysis and design agent-oriented based on POMDP are provided in the same time. Finally, the two case studies are given and the experimental results have shown efficiency and ration...

Understanding sorption isotherms is crucial in food science for optimizing the drying processes, enhancing shelf-life of food, and maintaining quality during storage. This study investigated sweet cherry powder (SCP) using static gravimetric method. The experimental water curves lyophilized were determined at 30°C, 40°C, 50°C. then fitted to six isotherm models: Modified GAB, Halsey, Smith, Osw...

In this paper, we present a geometric method for describing the effects of the delay induced uncertainty on the stability of a standard Smith Predictor control scheme. The method consists of deriving the stability crossing curves in the parameter space defined by the nominal delay, and delay uncertainty, respectively. More precisely, we start by computing the crossing set, which consists of all...

Smith was a pioneer epidemiologist, bacteriologist, and pathologist who made many contributions to medical science that were of far-reaching importance. He is best known for his work on Texas cattle fever, in which he and his colleagues discovered the protozoan agent and its means of transmission by ticks. This was the ¿ rst time that an arthropod had been de¿ nitively linked with the transmiss...

This paper proposes a new modified discrete Smith predictor control scheme for stable processes with dead time. The processes are assumed to be of stable first order with time delay, which are commonly used in process industry. The present scheme consists of two parts: predictive disturbance observer (PDOB) and Smith predictor structure. The PDOB scheme exhibits the property of DOB structure wh...

The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...

In an open-ended contingent valuation (CV) survey, a respondent can state any non-negative valuation for a given good. As the set of possible responses is infinite, the GibbardSatterthwaite theorem implies that such a survey cannot be incentive-compatible. That is, participants in an open-ended CV survey have an incentive to increase their utility by misrepresenting their preferences. This natu...
