Control design is often done based on simplified models. After design it is necessary to verify that the real closed loop system behaves well. This is mostly done by experiments and simulations. Theoretical analysis is an important complement to this that can help to verify critical cases. Structural information about uncertainties, time-variations, nonlinearities, and signals can be described by

Popular Abstract in Swedish En industrirobot är en flexibel programmerbar maskin som bör användas för sådant arbete som inte lämpar sig för människan att utföra. Olika tekniska begränsningar i dagens styrsystem begränsar dock robotars tillämpbarhet. Avhandlingen föreslår ett nytt sätt att bygga upp robotstyrsystem så att roboten på bästa sätt skall kunna tjäna människan.Industrial robots play a key role in manufacturing systems. Robots are distinguished from other types of machinery mainly on the basis of their programmability and ability to be adaptable to different tasks. The use of computer control to achieve desired flexibility implies that software issues for embedded control systems are central for the applicability and utilization of the equipment. The str

Popular Abstract in Swedish I de flesta reglerproblem är syftet att hålla utsignalen nära ett önskat värde trots störningar som påverkar systemet. Ibland är det bästa referensvärdet inte känt i förväg. I stället skall det hittas i realtid för att optimera systemets prestanda. Denna avhandling behandlar en så kallade probing-strategi som kan tillämpas för denna klass av problem. Fokus ligger i tillIn most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. The focus is on the application of the technique to the control of feed supply in

Frequency domain analysis and design of power systems is complicated in the presence of harmonics, switching dynamics, nonlinearities, unbalances, and for systems with mixed ac/dc dynamics. The reason is that linearization of the system does not lead to a time invariant system, but a system with periodically time varying dynamics, which implies that there is coupling between different frequencies.

Popular Abstract in Swedish Många olika proteiner kan produceras med hjälp av rekombinanta DNA tekniker. Ofta sätts vektorn som kodar för det rekombinanta proteinet in i bakterien E. coli, då den är välkänd. Det är viktigt att producera mycket celler för att uppnå hög produktivitet. Detta görs genom att näringsämnet (ofta glukos) tillsätts kontinuerligt till en så kallad semisats reaktor. TillsatsThe recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. This is obtained through fed-batch operation where the nut

Behovet av klimatreglering har ökat kraftigt sedan 1960-talet. Ett av skälen till detta är den ändrade byggtekníken, som innebär lättare konstruktioner med större inre värmebelastning från belysning, maskiner, personer och solinstrålning genom stora fönsterytor. De ökade värmebelastningarna kan klaras av med ett flertal olika klimatsystem. Dessa system kräver någon form av reglering. Under 1970-taResults from a research project supported by the Swedish Council for Building Research are reported. The main task was to improve climate control technology. The work was focused on digital control. It was split up into three main tasks: model building, design of regulators, and fullscale experiments. Several rooms, airducts, and heat exchangers were modelled. Simple dynamic models have been deriv
