    In a physical system several targets are normally being considered in which each of nominal and robust performance has their own strengths and weaknesses. In nominal performance case, system operation without uncertainty has decisive effect on the operation of system, whereas in robust performance one, operation with uncertainty will be considered. The target of present paper is a balance between nominal and robust performance of state feedback A new approach of present paper is the combination of two controllers of μ and H2/H∞.  The controller for robust stability status, nominal performance, robust performance and noise rejection are designed simultaneous. Controller will be achieved from solving constraint optimization problem. Where a simultaneous H2 /H∞/µ robust multivariable controller has been designed over an X-29 Single Person.  This model has three inputs and three outputs, where the state space equations of the system response to an unstable one. Simulation results show the effectiveness and benefits of the method.DOI:http://dx.doi.org/10.11591/ijece.v3i2.235

    Path Planning for Two-Link Navigation in an Unknown Environment using webcam

    In this article, we used image processing by a webcam connected on top of the arm robot. The robot navigation is in an unknown environment. Then start point and target point were determined for the robot, so the robot needs to have a program for path planning using Voronoi diagrams to find the path. After the possible path for moving the robot was found, the route information obtained was sent to the arm robot. The arm robot moves in the workspace and any time new information was processed via the webcam. The program was written using MATLAB software which at controls the robot’s movement the unknown environment

    After the COVID-19 pandemic and the consequent restrictions assigned by the National Committee on Combating Coronavirus (NCCC), the Ministry of Science, Research, and Technology (MSRT) set up committees to trace and analyze the outcomes of the pandemic. Objectives: This paper aimed to explain the policies, programs, and activities executed by MSRT and analyze the points of strength and weakness. Methods: In this report, the MSRT experience during the first wave of the COVID-19 pandemic in the Iran higher education (HE) system is briefly reported by referring to pieces of evidence documented by MSRT and analyzing strengths and, predicting the outcomes toward the future. The evidence was analyzed descriptively. Results: The policies, plans, and actions were based on three key policies including participation, adaptation, and tolerance. Conclusion: Iranian HE system has changed in many aspects during the recent months due to the COVID-19 pandemic. MSRT instantly reorganized its activities to coordinate its decisions with NCCC. Keywords: Higher Education, Coronavirus Pandemic, Iran
