A review: Front windshield wiper controller system for synchronisation of two wiper motors

Synchronisation of motors is required in applications, where two or more motors are used. Conventional Tandem motion uses the high speed DC motor; where it is problematic to vary the speed of the wiper arms. Also there are weight and space constraints. In proposed system a pair of synchronized windshield wipers is used, in which each wiper arm is driven by its own independent motor. Traditional rigid mechanical linkages, driven by a single DC motor are removed for the sake of weight and space. For synchronisation and to avoid collision a closed loop control system is used. By Synchronising Two DC Motors, which are controlled using Peripheral Interface Controller (PIC) or Field Programmable Gate Array (FPGA), problems regarding Weight and Space can be solved. At present, synchronisation is achieved using Digital Signal Processor (DSP). As Cost of DSP is more, it is proposed to implement design using PIC. Also to get more design flexibility, system is implemented using FPGA. The results, which are going to obtain with PIC or FPGA, have to compare with the results that have obtained with existing method of Synchronisation by using DSP.
