Swarm control is an open problem. We are taking steps for systematic flight control of large numbers of UAVs. In this paper, we present our design and implementation of UAV group control in a fully implemented simulated UAV environment. We explore issues of limited user intervention, novel agent personality, and multi-theater load balancing.

The combination of different desirable characteristics and situation-dependent behavior cause the design of adaptive cruise control (ACC) systems to be time consuming and tedious. This chapter presents a systematic approach for the design and tuning of an ACC, based on model predictive control (MPC). A unique feature of the synthesized ACC is its parameterization in terms of the key characteris...

Disturbances in the form of oscillations are usually originated in process plants due to various faults such as sensor faults, valve faults, process faults and controller tuning faults. Many of these faults can be represented as nonlinearities. Faults in the form of nonlinearities may produce oscillations with a fundamental frequency and its harmonics. This study presents a novel method based o...

To substantially improve operational control of complex industrial plants, it is important to be able to predict the influences which process variables have on qualityrelevant target variables. The determination of influencing relationship and also the delay-time behaviour of various industrial processes makes it difficult to synthesis a quality prediction system. A hybrid modeling method combi...

control chart is the most well-known chart to monitor the number of nonconformities per inspection unit where each sample consists of constant size. generally, the design of a control chart requires determination of sample size, sampling interval, and control limits width. optimally selecting these parameters depends on several process parameters, which have been considered from statistical and...

the intervention of urban design in irans architectural structures has been for many years a challenging issue for architects and urban designers over their professional realm. the preservation of architectural structures in iran has always resorted to extremes. this control and direction has sometimes resulted in exclusion of architecture position and has sometimes, once faced with lack of pro...

Product functions, assembly and disassembly processes largely depend on the connections that are holding the product’s components together. In general, the disconnecting process of established connections is sub-optimal, which often remains unnoticed until maintenance or recycling requires disassembly work. Sometimes connections were optimised to improve the disconnecting processes, but usually...

This paper gives a systematic way to design time-variant feedback control laws for a class of controllable non-linear systems. This class contains a lot of systems which cannot be stabilized via a time-invariant feedback control law. The interest of this work lies in the design method since a general existence result is already available. The techniques employed here are basic: they mainly invo...

This paper is concerned with integration of classical control criteria into the H∞ robust control design with the use of the H∞ Loop Shaping Design Procedure (LSDP) by McFarlane and Glover. Classical control criteria such as gain crossover frequency and phase margin still play important roles to designing and evaluating feedback control systems in practical applications including Hard Disk Driv...

در این رساله عملکرد یک موتور توربوپراپ که ملخ آن از نوع clark y 5868-r9 است در شرایط نقطه طرح (on- design) و خارج از نقطه طرح (off- design) مورد مطالعه قرار گرفته شده است. موتور توربوپراپ یکی از انواع موتور جت در تراست بالا و مصرف مخصوص سوخت پایین است که عدد ماخ پروازی آن هرگز از 8/. تجاوز نمی کند. دور موتور های توربوجت به حدی زیاداست که در صورت اتصال مستقیم به ملخ، سرعت نوک تیغه های ملخ به سرع...
