Motor controllers are expected not only to control the speed and position of the motor, but also the operation of the motor to both regulate energy consumption and implement other functions to meet design requirements. Advanced DSPbased MCUs use advanced algorithm control to improve system performance and reduce system cost. These additional functions range from power factor correction to Ether drivers and TCP/IP protocol stacks. Depending on the application requirements, the system plexity ranges from the minimal dc brush motor controller to highend vector drives. For the simplest control systems, all that may be needed is a microcontroller (MCU) that offers the requisite motor control peripherals (see Fig. 1). For example, a dc brush motor controller in an automotive power mirror application is served easily by a simple MCU. Fig. 1. A robust controller improves system integration. The main vehicle controller then integrates functions, such as settings for multiple drivers and so on, around the MCU module. Another example of such simple control systems is a stepper MCU IC that manages a stepper motor, and may operate under the supervision of another part of the system. Realworld applications A more sophisticated system, where greater performance is needed, can use a smarter algorithm in a programmable processor to improve system performan
