A PIλDμ controller design for peltier-thermoelectric cooling system

Abstract

This paper describes the fractional-order controller design to achieve stability, performance and robustness of peltier-thermoelectric cooling system modeled as a first-order plus dead-time process which is widely used in a variety of applications. By using the purposed method, the process parameters are estimated from experimental based model identification. Then, the fractional-order controller is designed and optimized by minimizing the function of ISE performance index. Simulation validates theoretical analysis and demonstrates the enhanced performance of the fractional-order controller compared with integer-order.
