A DSP based efficient and intelligent coordinated controller for a Gas cooker and hood integrated system

A control system, using a TMS320F28035 as the main control chip, for a sinusoidal wave BLDC motor in applications of range hoods is proposed to realize speed automations, noise reductions and energy efficient usages. In the proposed control system, the control module of BLDC motors is based on an IPM intelligent system, and the software based on sinusoidal wave controlled SVPWM. An anti-saturation PI algorithm is introduced and implemented. The rotor position is determined from software identification technique and the introduction of leading angles in commutation processes to obtain the maximum output torques in a maximal exciting current. The experimental results have demonstrated that that the prototype system is an efficient, low noise, intelligent, low cost one.
