A Comparative Analysis of SIMC-PID with Other Conventional Techniques for Automobile Vehicle Air Conditioning System Control

Decreasing the thermal increase inside vehicles and safeguarding suitable vehicular temperature levels may result in improved vehicle fuel economy, reliability and passenger comfort. However, getting suitable techniques to attain this has been a great challenge to the system engineers. Although, the use of conventional techniques have proffered a great insight in solving the problem of temperature control in air conditioning system, however, they suffered from inefficient and non-lasting solution to the heat generated within the cabin walls. Thus, in this present paper, a Simple Internal Model Control based Proportional Integral Derivative (SIMC-PID) controller for automobile vehicle temperature is proposed. The SIMC method is based on the internal model control (IMC) theory and proposes a simple methodology for the tuning of the PI and PID industrial controllers. The suggested approach is compared with the conventional tuning methods such as Zeigler-Nichols, Cohen-Coon and Chien-Hrones-Reswick based on energy conservation and mass balance principles. Results obtained showed that the proposed SIMC-PID method could be of great significance in controlling the air-conditioning system temperature compared with the conventional tuning techniques.
