This article presents the performance tests, by simulation, of a classic PI speed controller applied to a switched reluctance motor (SRM) 8/6. The motor is represented by a linearization of the simplified non-linear model at an operating point set at 2000rpm. The model includes Coulomb plus viscous friction nonlinearity and an ideal inverter circuit. The control system simulations that are carried out are divided into two types: regulation tests and tracking tests, all simulations are carried out in Matlab® / Simulink software.

This work presents the process of obtaining the simplified model of a switched reluctance motor (SRM) 8/6. Subsequently, the structure of the single-phase model is analyzed, obtaining an exact linearization and zero dynamics of the system. Finally, the model is linearized at an operating point set at 2000 rpm The model includes Coulomb plus viscous friction nonlinearity and an ideal inverter circuit based on bridge converter topology. The simplified and linear models are simulated and compared in the Matlab®/Simulink software in order to validate the design of a classic controller using the linear model.

Social entrepreneurship focuses on the development of projects that seek to solve social problems. solve social problems. Currently there is a growing environmental awareness in the population, derived from climate change, where the use of renewable energies is a viable alternative. renewable energies, especially solar energy, is a viable alternative. This article aims to characterize the factors that prevent entrepreneurs from entering this market sector. The relationship between business, private sector and government is explored. The research paradigm is quantitative, based on a descriptive, non-experimental and cross-sectional study. Dscriptive, non-experimental and cross-sectional study. An online questionnaire was applied, structured by 11 questions. It was applied to 40 public servants performing administrative functions in the city of Cuenca, Ecuador. It was validated by means of Cronbach’s Alpha test with values 0.79≥X≥0.81. A topic that has been studied from different been studied from different perspectives is the profile of the entrepreneur and the regulatory barriers that can hinder the development of proposals that promote environmental conservation, enhanced by sustainability studies through the responsible consumption of natural resources. The implementation made it possible to improve the planning of processes at the institutional level and to schedule the execution of activities that ensure the mission, an element that influences institutional administrative management.
