Abstract
The speed control of two mass drive systems is presented in this paper. For the purpose of analysis, PI, Linear Matrix Inequality controller and Internal Model Controller are chosen. Tuning of PI controller is achieved by Zeigler Nichols method, whereas the LMI and IMC are adapted with the conventional method of tuning. The various simulations are carried out in order to analyze the performance index of these controllers and to fix the best controller, and the results are compared
Highlights
The idea of drive systems is used by most processing industries, such as paper mills, textile mills and elevator control mechanisms, which means that a motor has been linked via a shaft to a load
Proportional Integral (PI), Linear Matrix Inequality (LMI) and Internal Model Controller (IMC) controllers were introduced by adapting Ziegler Nichols and traditional tuning methods to two mass drive systems
The formula calculates the gain and the PI controller is tuned with the help of the Ziegler Nichols method and the response is obtained for the LMI controller
Summary
The idea of drive systems is used by most processing industries, such as paper mills, textile mills and elevator control mechanisms, which means that a motor has been linked via a shaft to a load. These implementations are commonly known as electro-mechanical system [1]. LMI's controller architecture is based on mathematical derivation This requires the conversion process of the transfer function to variables of the state space. The mathematical derivation involves the method of decreasing the function of higher order transfer to the function of first order transfer This process is called as half rule method. The organization of the rest of the paper can be described as follows in [II] process dynamics, and [III] controller implementation, continues with [IV] simulation results and [V] conclusion of the work
