In this paper, Fractional Order Proportional Integral Derivative Controller (FOPID) is designed for liquid level control of a spherical tank which is modeled as a First Order Plus Dead Time (FOPDT) system about an operating point. The response of designed FOPID controller is compared with the traditional integer order PID (IOPID) controller in simulation(More)
In this paper, Fractional Order Proportional Integral (FOPI) controller is designed for a liquid level control in a spherical tank which is modeled as a Fractional Order System (FOS). The performance of FOPI controller is compared with the traditional Integer Order PID (IOPID) controller designed for the same spherical tank which is modeled as a First Order(More)
The idea of fractional order controllers dawned with the exploration of fractional calculus. Since then these controllers have played an inevitable role in the process industry. Fractional order PID controllers have two more parameters unlike the conventional PID controllers. Over the years various tuning rules have been formulated and applied. The Internal(More)
The objective is to design controllers using different optimization techniques for pH Neutralization process. Controlling of pH in neutral region is an important process as small change in input gives the huge change in the output. The controller is designed using the Optimization techniques like BFO and PSO Algorithm. Comparison between BFO and PSO based(More)
