A novel PSO-based hybrid PV-FC-Diesel-Battery electric PID-controller drive system for electric vehicle traction

This paper presents a novel PID self regulating tri loop controller for a hybrid PV-FC-Diesel-Battery powered all-wheel drive electric vehicle using four Permanent Magnet DC (PMDC) motors, which are modeled to include existing nonlinearities in motor plus load inertia (J) and viscous friction (B). A Tri Loop dynamic error driven scheme is based on Multi Objective Particle Swarm Optimization MOPSO and proposed to regulate motor current against high inrush currents and motor overloading conditions, in addition to motor speed dynamic reference tracking. The Proposed tri loop dynamic error driven PID self tuned controller is also used to ensure energy efficiency, control loop decoupling, stability and system efficient utilization while maintaining full speed tracking capability. The integrated scheme is fully stabilized using a novel FACTS based green filter compensators developed by First Author that ensures stabilized DC bus voltage, minimal inrush current conditions, and damped load excursions.
