A control apparatus and method of a motor-driven power steering system are provided. The apparatus and method are capable of suppressing catch-up that occurs at a high steering speed even without using an expensive motor, thereby contributing to improving commercial value and reducing the manufacturing cost of a vehicle. The method includes determining a target steering speed using driver-steering input information and vehicle state information and determining the target steering speed corresponds to a condition for avoiding catch-up using the determined target steering speed. A current compensation value is then determined for reducing catch-up using the target steering speed in response to determining that is the target steering speed corresponds a condition for avoiding catch-up and motor current is compensated with the current compensation value.
