Design of PID Controller for Magnetic Levitation System using Harris Hawks Optimization

In most real-time industrial systems, optimal controller implementation is very essential to maintain the output based on reference input. The design problem becomes a complex task when system model greatly non-linear and unstable. proposed research aims finest PID for unstable Magnetic Levitation System (MLS) using Harris Hawks Optimization (HHO) algorithm. MLS highly electro-mechanical hence of task. work implements one Degree Freedom (1DOF) 2DOF system. this work, designed with two-step process; (i) Initial optimization search find P-controller (Kp) gain stabilize (ii) Tuning integral (Ki) derivative (Kd) gains reduce deviation between input output. performance validated servo regulatory operations result study confirms that method helps get better error value time domain specifications compared other available methods.
