This paper provides design and implementation of a DC-DC boost converter control system by using gain scheduling PI-controller to achieve stable regulated output voltage with improved dynamic performance. The proposed controller parameters are obtained from system output response based on step input signal. A test step input is applied to the system and the three parameters of the plant are obt...

PVSio is a conservative extension to the PVS prelude library that provides basic input/output capabilities to the PVS ground evaluator. It supports rapid prototyping in PVS by enhancing the specification language with built-in constructs for string manipulation, floating point arithmetic, and input/output operations.

In this paper we consider the problem of desynchronising modular synchronous speci cations for their realisation into GALS architectures and obtaining simple wrappers that are e ciently synthesisable using existing synthesis tools. The systems are modeled using Petri nets (PN) and the desynchronisation technique is based on the theory of PN Localities. The ring semantics of a globally synchrono...

We propose the Probabilistic Timed I/O Automaton (PTIOA) framework for modelling and analyzing discretely communicating probabilistic hybrid systems. State transition of a PTIOA can be nondeterministic or probabilistic. Probabilistic choices can be based on continuous distributions. Continuous evolution of a PTIOA is purely nondeterministic. PTIOAs can communicate through shared actions. By sup...

We present an abstract framework for sequence testing that is implemented in Isabelle/HOL-TestGen. Our framework is based on the theory of state-exception monads, explicitly modelled in HOL, and can cope with typed input and output, interleaving executions including abort, and synchronisation. The framework is particularly geared towards symbolic execution and has proven effective in several la...

From the past literature survey, it is witnessed that there is remarkable growth in the Wind power capacity in the recent years. The advancement of converters used in wind power technologies led to maximum extraction of wind energy. In this paper, a comparison of Single Boost converter (SBC) with Interleaved Boost Converter (IBC) used in small-scale wind turbine systems. It utilizes the AC-DC-A...

A boost converter which employs an isolated active snubber to reduce the losses caused by the reverserecovery characteristic of the boost rectifier and the turnon discharge loss of the output capacitance of the boost switch is described. The proposed isolated active snubber consists of a coupled inductor, clamp capacitor, and ground-referenced N-type MOSFET. The performance of the proposed conv...

We consider the problem of verifying finite precision implementation of linear time-invariant controllers against mathematical specifications. A specification may have multiple correct implementations which are different from each other in controller state representation, but equivalent from a perspective of input-output behavior (e.g., due to optimization in a code generator). The implementati...
