The performance of generalized minimum variance (GMV) is examined when applied to the wastewater pH control of waterborne paint production process. The control strategy is tested under batch coagulation condition on the wastewater. Al-2(SO4)(3) is chosen as coagulant. Ca(OH)(2) is used as manipulating variable while H2SO4 is fed continuously at constant rate. The evaluated parameters of the GMV algorithm are employed precisely in the control law computation. The success of the control action is estimated using negative maximum error, the first set point reaching time, and offset. The constant offset problem is experienced with the GMV control. This offset is reduced by employing a reduction of coagulant amount.
