Gas turbines are used as main engines to convert fuel energy into
mechanical energy used to move the generator and thus produce
electrical power at the power plants. When you use a gas turbine in
the power plants, it must maintain a constant speed
of the turbine
and thus fixed frequency output of the current also must maintain
the parameters of the turbine such as pressures and temperatures at
the limits and thus extend the life of the turbine components and
increased efficiency. there was a need for the design of control
systems maintain a constant speed of the turbine and to avoid
operating at others and allowed values. In this research, we modeled
the gas turbine and solving the model using MATLAB/ SIMULINK
program, and then design a proportional integral differential
controller for gas turbine operating In Gandar Station
