Electrical and Control Engineer

I have done my MS in Control Systems and have been working as an Automation Engineer for 4 years. Currently, I am attached with a public sector organization, where I work as Logic Developer and Commissioning Engineer. Other than having expertise in providing Siemens based control solutions, I like to research the field of Theoretical Control. It makes use of mathematical concepts to derive, apply and then simulate the control techniques. This framework has allowed me to not only have grip on software like MATLAB, but also on solving general research and modelling problems.

A little snippet of the code is displayed. This was implemented as part of project that involved control of a steam turbine. The filter was implemented in SCL Language for Siemens S7-400 CPU.

When multiple sensors are available for measuring conditions in a controlled process, a cascaded control system can often perform better than a traditional single-measurement controller. I programmed and tunned a cascaded PID control for a governor valve of a steam turbine using steam pressure and generated power as feedback. Any disturbance in such a system is first manifested as a variation of steam pressure, so it was used as an inner control loop. This disturbance then propogates to change the generated power of the turbine which was controlled in the outer loop. The inner loop was tuned to respond faster to the error signal as compared to outer and slower loop. The result was a smooth control of turbine power and robustness to the power and pressure surges. The system was implemented using Siemens S7-400 PLC based system in redundant configuration.

Raheel was the only one of the bidders who pointed out the need to verify the results, and eventually worked hard on that, going beyond the scope of the project. While the project took longer than expected, it is partly because of the client (myself), so I can freely recommend Raheel for Matlab projects.

Experiencia

Application Developer and Commissioning Engineer

Public Sector Organization
ene 2016 - Presente
I work as an Automation Engineer and have delivered multiple complex control projects. I provide complete programming, visualization and configuration services along with commissioning data and instructions to implement software part in the system. I have developed expertise on Siemens PLC based systems, peripherals and protocols. I am incharge of meeting requirement specifications exactly such that the software part smooothly works with the hardware setup.

Research fellow

Pakistan Institute of Engineering and Applied Sciences
nov 2013 - nov 2015 (2 años)
I carried out theoretical research in the area of networked control system and developed a bandwidth efficient control architecture. It was based on real-time optimization of system sampling frequency to tackle the transmission delays between sensors and controller. A stochastic switching control was then proposed to guarantee stability of the closed loop system. My thesis got accepted in EPSR journal by Elsevier.

Android Based ECG Monitoring System

IJSR
This document presents the development of a low power and portable ECG monitoring device based on MSP430 microcontroller and an Android Phone. This work is done in order to provide a reliable solution for cardiovascular patients who can analyze their ECG easily. An attempt is made to reduce cost, energy requirements and increase portability of the system.

Power system stability enhancement over a network with random delays

IEEE
The emergence of conventional electrical grid into smart grid has enabled the use of networked controllers for power system control applications. This article discusses the rotor angle stability enhancement of a power system using networked control, where the channel has random delays. An optimal stochastic control is designed to damp the oscillations in power system and compensate the delay effects using probability distribution of delays.

Networked control of a power system: A non-uniform sampling approach

EPSR, Elsevier
This article deals with the damping of low-frequency power systems oscillations using a networked controller on Smart Grid. The contribution of the paper is a bandwidth efficient delay compensation technique and its application to power systems stability enhancement in a smart grid.
